Debian Package Managers
In terms of how software is installed, every Linux distribution is unique in its own way.Linux distributions employ a variety of installation file formats, package managers, and command line options to complete the installation process.Even within a single version of Linux, there are a variety of different package managers to choose from.
We will cover how to install software on a Debian-type Linux system, how to utilize a couple of the many Debian package managers and installers, as well as some important information regarding Debian files and repositories, in this post.Introduction: Debian Linux systems make use of deb installation files to get up and running.The ″.deb″ file extension is used for these types of files.Ubuntu, Finnix, Knoppix, Debian (the source of the package name), Linux Mint (Debian Edition), MintPPC, Linspire, MEPIS, and a slew of other Debian-based operating systems are examples of Debian systems.A Debian file has the Internet media type application/x-deb as its Internet media type.
- The Debian file itself is composed of two tarballs (tar files; Tar files do not compress files) that have been compressed together as a single file using gzip, xz, lzma, or bzip2 compression algorithms.
- A portion of the program data is contained in one of the tar files, while the other includes control information such as the package’s name, version, description, and so forth.
- Package managers often download Debian packages from a software repository, which is where the files are stored.
- A repository is a collection of Debian files that is often sourced from a server or other remote place and is maintained by the project.
- Package managers gain access to these repositories and download the Debian file that has been requested.
The package manager then goes ahead and installs the software.It is possible to utilize a package manager to handle the installation, removal, setup, and upgrading of applications and drivers on a computer system using specialized software.Instead of downloading a Debian file from a repository, the user downloads or creates a Debian file on their own computer.It is still possible to install the local file; Debian files do not have to originate from a repository, although the vast majority do.NOTE: Regardless of where the Debian files are obtained or how they are installed, root privileges are necessary for the installation process.
User input for graphical applications (i.e., programs that are not command-line based) will be required.It is important to remember to type ″sudo″ before any commands while working from the command-line.If the current user is root, then root does not need to type sudo to complete the operation.Before we go into package managers and installation, it’s vital to understand how packages are currently configured.When managing packages, the software packages may be in any of a number of different states at the same time.
When a package has the condition ″not-installed,″ it means that it is not currently installed on the system, and that no leftover files are present.When a package installation has begun but has not been completed due to a variety of factors, the ″half-installed″ state is created.The ″config-files″ status indicates that a package has been uninstalled, but that configuration files have remained in one or more of the system’s folders after the program has been removed.The presence of a config file within the home folder is not taken into consideration.) The ″unpacked″ condition signifies that a package has been uncompressed and that the files are no longer combined into one.
- Unpacking a ″half-configured″ deb file causes the configuration to begin, but it does not complete the process.
- Files in the ″triggers-awaited″ state are awaiting a trigger from another package to be applied to them (s).
- The condition of ″triggers-pending″ indicates that the package has been triggered but has not yet been delivered.
Another state is ″installed,″ which means that the files in this state have been completely and successfully installed.Additionally, there are package selection flags.When deciding which packages to install, they will be in one of many states depending on their status.The ″install″ flag indicates that the program has been designated for installation.Using the ″hold″ flag specifies that the package will not be installed until a later time.
The ″deinstall″ flag indicates that a program should be deleted.The ″purge″ flag works in the same way as the ″deinstall″ flag, with the exception that the configuration files are also deleted.There is only one package flag to be aware of: reinst-required.Software that has been marked with this flag cannot be removed from the system unless it is forced to be removed.
- This particular collection of software has become corrupt, and it must be rectified by reinstalling it.
- These flags and states are used by a large number of package managers.
- Understanding these concepts is beneficial when working with a package management.
Command-line: There are a number different ways to install Debian files via the command line.If the file is on your computer, open a terminal and execute ″dpkg -i package.deb″ to install it.Replace the word ″package″ with the name of the file you want to open.The default package manager in Debian is represented by the command ″dpkg.″ It is a program that runs from the command line.The ″-i″ argument indicates that the file is to be installed, and it is followed by the path to the file to be installed.
If you want to install software from a repository, run ″apt-get install PACKAGES″ in the terminal.Users may enter a single package or a list of several packages separated by spaces.To add a repository, run the command ″add-apt-repository ADDRESS,″ where ADDRESS is the location of the repository.PPA repositories (Personal Package Archive) repositories are the most frequently added repositories by users.The majority of these repositories are hosted on the website Launchpad.com.For instance, the command ″add-apt-repository ppa:noobslab/icons″ would add a PPA to the system.
- WARNING: When making package modifications, the user is asked before the changes are implemented.
- Additionally, while installing packages, information about the amount of disk space that will be used and the software that the package requires is printed to the terminal.
- The command ″dpkg-reconfigure PACKAGE″ is used to repair packages from a terminal, where PACKAGE is the package that has to be fixed.
- In order to inspect the contents of a deb file, users can use a terminal to run the command ″dpkg -x PACKAGE.deb./PATH″ in order to unpack the file.
- PACKAGE should be replaced with the name of the package, and PATH should be replaced with the location of the output.
- Using a terminal, execute the command ″dpkg -r PACKAGE″ to delete or uninstall software.
- NOTE: When referring to a software package’s file, be sure to provide the file extension as well as the location to the file.
You should not include the extension ″.deb″ after the name of a package when referring to it that has been installed or that is in a repository.Package managers with graphical interfaces: Some people are not fond of command-line interfaces.There are a plethora of alternatives, which is a blessing.Visual package managers are interfaces between the Advanced Packaging Tool and the end user (APT).Thus, graphical package managers (GPMs) serve as a Graphical User Interface (GUI) for the APT command-line tools.After the user enters the information into the graphical application, the frontend makes use of the command-line tool to process the input.
Some of the package managers are explored in further detail under the following headings, although this is by no means an exhaustive listing.Synaptic: Synaptic is a powerful package manager that allows you to install deb packages from a variety of sources.Users may search for packages and then right-click on the ones they want to install.Install, reinstall, uninstall, complete removal, upgrade, and unmark are among the available options.
- Removal of the program and configuration files is accomplished by ″complete removal,″ whereas ″removal″ merely removes the software.
- ″Unmark″ is used when a user marks a change (for example, designating a package for removal) and then determines that the change should not be made.
- After the user has indicated the changes they wish to make, they may proceed by clicking ″Apply.″ The ″Reload″ button is used to refresh the program list by scanning the repositories, which is done by pressing the button.
- ″Mark All Upgrades″ identifies all of the newer versions of software that can be used to update the older versions of software that are currently installed.
- Users can organize packages into groups by selecting the appropriate buttons on the bottom-left side of the screen.
Users can then select a group from which to conduct searches inside that group.A few examples of groups are: all, uninstalled (not installed), installed (not installed), development (LP-PPA-noobslab-themes/raring), noted changes (arch: amd64), and many more.″All″ would refer to each and every shipment.The terms ″Not Installed″ and ″Installed″ would refer to packages that have not been installed and packages that have been installed, respectively.Applications for software development, such as Geany or Eclipse, would fall under the category of ″development.″ ″LP-PPA-noobslab-themes/raring″ is a repository that contains themes.
″Marked changes″ refer to software modifications that have been made by the user but have not yet been implemented.″arch: amd64″ refers to software that has been specifically built for AMD64 CPUs.There are a plethora of more groupings and classifications.The majority of them are self-explanatory.GDebi: GDebi is not a package manager; it just installs local deb files and does not manage any packages.
This application can also be run in a terminal window if desired.To utilize the GUI, right-click a deb file and select ″Open with GDebi″ from the context menu.After that, GDebi appears, displaying information about the package.There is a lot of information in this package, including a description, version, necessary files, files contained in the package, and other things.When a user wishes to fast install a local file, GDebi is the tool to utilize.The installation is quick, and GDebi does not need a significant amount of RAM or CPU resources.
- APTonCD: APTonCD is not a package manager in the traditional sense.
- As an alternative, users can create a CD that has all of the Debian files for the software that has been installed on the machine using this program.
- This, however, would only work if the Debian cache had not been deleted before.
- For example, the directory path /var/cache/apt/archives refers to a folder that includes debs that have been archived.
- When a software is installed, the package management downloads the deb file to this location and places it in the application directory.
- These files are retained as a backup in case something goes wrong.
- APTonCD burns a disc with all of these debs or produces an ISO file from them (virtual disc file).
- This enables administrators to use this disc to install the same software on multiple systems that must be identical to the original machine.
- This disc can also be used as a backup disc for the packages included inside.
- This page contains information on the Ubuntu Software Center, which is a Debian package manager that is tailored to the Ubuntu distribution.
- This package manager has been created to be simple to use.
- Ubuntu Software Center is not a sophisticated program in the same way that Synaptic is.
- Ubuntu Software Center, on the other hand, was created with general consumers as a priority.
- The package manager is really straightforward.
- The main screen features a list of program kinds to the left of the screen, as well as a collection of popular and new apps in the middle of the display.
- Users will find huge buttons for installed apps as well as a list of all programs in the top bar.
- Because of the straightforward appearance, this package manager should be self-explanatory; users should have no trouble figuring out how to make use of this application.
- This package manager allows users to rate and evaluate the applications.
- This will assist Ubuntu users in avoiding software that is defective or harmful.
- The Package Manager Systems’ List File contains the following information: It is necessary for the effective operation of package managers on Debian-based Linux systems that certain system files are present and accessible.
- There is one in particular that consumers need to be aware of and comprehend.
- The file /etc/apt/sources.list is a plain text file that contains a list of repositories that are available on the system.
Package managers read this file and use the addresses in it to compile a list of packages that can be installed, which they then distribute to users.This file contains commented lines (also known as ignored lines) that begin with the pound sign ( ).Additions and deletions of repositories are possible through the use of a package manager or by editing this file.Disabled repositories are marked as such by using the pound symbol () at the beginning of the command line.
- Below are two examples of lines to consider.
- debsaucy main limited access code deb-primary srcsaucy’s directory is limited It is indicated by these two lines that the repositories provide binary (compiled) and source code packages, respectively, in their respective repositories.
- Following that, the address is provided.
- This information is followed by the operating system version, which informs which software is compatible with the system.
- In this instance, the field contains the word ″saucy.″ This is the codename for Ubuntu 13.10, which will be released in the near future.
- Installing software for Ubuntu 14.04 or Debian (Wheezy) on this system will prevent it from working properly.
- Last but not least, the repository type is specified (this is used by Ubuntu systems).
- The available strings for this field are main, main restricted (or just restricted), universe, and multiverse.
- Main is the most often used string.
Canonical provides license and support for the software in accordance with these terms (makers of Ubuntu).Basics – This is open-source software that is sponsored by Canonical.VLC Media Player, Firefox, Thunderbird, and Clementine are just a few examples.Restricted – This program is subject to license limitations that prohibit it from being distributed, modified, or copied, among other things.This collection of software includes useful applications that Canonical provides support for.
Although MP3 codecs and RAR are widely used, neither the MP3 codec nor the RAR program is available as freely distributable or free open-source software.Universe – Software downloaded from a PPA (such as Launchpad) or an open-source website (such as Sourceforge) would fall under this category.Despite the fact that this program is free and open-source, Canonical does not provide any support for it.
- Noobslab’s icons and themes, for example, are a good illustration of this.
- Multiplexed – This category contains closed-source software that is subject to licensing restrictions and does not get any support from Canonical.
- Examples of this sort of software include Linux video games acquired from a third-party firm that has no links with Canonical and that are not supported by Canonical.
- Additionally, free, closed-source software such as Opera may be included in this group.
The term ″non-free″ relates to the multiverse.It is possible that users may notice the phrases stable, backports, suggested, updates, and security in the text.Software that is stable and designed for general usage is described as follows: Testing – This software is still in the testing phase, but it is expected to become part of the next stable release in the near future.
- Unstable – This program is brand new and is not yet suitable to be classified as ″Testing.″ Known as backport repositories, these repositories include updates that are not supported by Canonical.
- Changes that have been suggested – These updates have been proposed.
- In addition, Canonical supports these updates and employs them to ensure that they are stable before distributing them through its software update repository.
These repositories provide generic updates, such as upgrading Firefox from version 33 to version 34, and are categorized as such.Security – This category of software contains updates that are directly related to security.
What two Linux distributions utilize the Debian package manager by default
- When it comes to software installation, every Linux distribution is different.
- Various Linux distributions use a variety of installation file types, package managers, and command line options to complete the process of installation.
- It is possible to have multiple types of package managers even within a single version of Linux.
- We will cover how to install software on a Debian-type Linux system, how to use a few of the different Debian package managers and installers, as well as some useful information about Debian files and repositories, all in this article.
- Introduction: deb installation files are used on Debian Linux systems.
- The ″.deb″ file extension is used for these types of documents.
- Ubuntu, Finnix, Knoppix, Debian (the name of the operating system from which the package was derived), Linux Mint (Debian Edition), MintPPC, Linspire, MEPIS, and many other Debian-based systems are examples of such systems.
- It is application/x-deb that is used as the Internet media type for a Debian file.
- The Debian file itself consists of two tarballs (tar files; Tar files do not compress files) that have been compressed together as a single file using gzip, xz, lzma, or bzip2 to form a single file for distribution.
- A portion of the program data is contained in one of the tar files, while the other contains control information such as the package’s name, version, description, and so forth.
Package managers typically download Debian files from a software repository, which is where the files are created.In the Debian operating system, a repository is a collection of Debian files that typically originates from a server or other location.Debian files are downloaded by package managers after they have accessed these repositories.The package manager then goes ahead and installs the package on your computer.
- It is possible to use a package manager to handle the installation, removal, configuration, and updating of software and drivers on a computer system.
- A Debian file is downloaded or created by the user if one is not found in a repository or downloaded from one.
- Debian files do not have to come from a repository in order to be installed; however, the majority of Debian files do.
- NOTE: Regardless of where the Debian files are obtained or how they are installed, root privileges are required for the installation process to take place successfully.
- Graphical programs (programs that do not run from the command line) will prompt the user for the root password.
Always remember to type ″sudo″ before the command when working from the command-line.It is not necessary to type sudo if the currently logged-in user is root.It is necessary to understand some package states before discussing package managers and installation.If you are managing software packages, the software packages could be in any of a number of different states.When a package has the state ″not-installed,″ it means that it is not currently installed on the system, and that no residual files are present in its location.
In the case of a package installation that started but did not complete for some reason, the ″half-installed″ state is achieved.An uninstalled package has the ″config-files″ state, which indicates that configuration files have been left behind in one or more of the system’s directories.The presence of a config file within the home folder is not taken into consideration.″Unpacked″ indicates that a package has been uncompressed and the files are no longer in a single folder.Unpacking a ″half-configured″ deb file causes the configuration to begin, but it does not complete the task.
When a file is in the ″triggers-awaited″ state, it is waiting for another package to trigger it (s).″Triggers-pending″ indicates that the package has been triggered and is waiting for further instructions.There is also a state known as ″installed,″ which indicates that files in this state have been correctly and completely installed.
Flags for selecting specific packages can also be used.A variety of states will be available when choosing which packages to install.The ″install″ flag indicates that the software is ready to be installed on your computer.Using the ″hold″ flag indicates that the package will not be installed until a later date.Using the ″deinstall″ flag, you can mark applications that should be removed from your computer.
- This flag works in a similar way to ″deinstall,″ except that the configuration files are also removed when using this flag.
- Reinstalling a package is indicated by the reinst-required package flag.
- Remove software from the system that has been marked with this flag will not work unless you force it to do so.
- Software that has become corrupted must be repaired by reinstalling it.
- These flags and states are used by a large number of package management programs (PM).
- These definitions are important to know when working with a package manager.
- Command-line: There are a couple of different ways to install Debian files from the command-line.
- The command ″dpkg -i package.deb″ in a terminal will work if the file is located on your computer’s local hard drive.
- The name of the file should be substituted in for ″package.″ dpkg is the package manager that comes standard with Debian.
- An application that runs from the command line When using the ″-i″ parameter, you are specifying that you want to install something, and then you are specifying the path to the file to install.
- The command ″apt-get install PACKAGES″ will install software from a repository in the terminal.
- Several packages may be listed at the same time by using a space between each entry.
- The command ″add-apt-repository ADDRESS″ will add a repository to your system, with ADDRESS representing its location.
- PPA repositories (Personal Package Archive) repositories are the most frequently added by users.
The majority of these repositories are hosted by the website Launchpad.net..For instance, the command ″add-apt-repository ppa:noobslab/icons″ would add the following PPA to the system: When making package changes, the user is prompted before the changes are implemented.When packages are installed, information about the amount of disk space that will be used and the software that the package requires is printed to the terminal.The command ″dpkg-reconfigure PACKAGE″ is used to repair packages from a terminal window.PACKAGE is the package that needs to be repaired.In order to view the contents of a deb file, users can use a terminal to run the command ″dpkg -x PACKAGE.deb./PATH″ in order to unpack the package.
PACKAGE should be replaced with the name of the package, and PATH should be replaced with the output directory path.Using a terminal, type ″dpkg -r PACKAGE″ to remove or uninstall software.Please remember to provide the file extension and the file location when referring to a software package’s file.The suffix ″.deb″ should not be used to refer to installed packages or a package in a repository when referring to either.GIMP-based package managers are a graphical user interface for managing packages.CLI commands are not popular with all users.
It’s a good thing that there are so many other possibilities available.The Advanced Packaging Tool is accessed through the graphical package managers (APT).Therefore, graphical package managers (GPMs) serve as a Graphical User Interface (GUI) for the APT command-line tools.
After the user enters the information into the graphical application, the frontend makes use of the command-line tool to complete the task.Although some of the package managers are described under the following headings, this is not an exhaustive list of all of them.Synaptic: Synaptic is a powerful package manager that allows you to install deb packages from a variety of sources.Searching for packages is possible, and users may right-click on the packages they want to use.Install, reinstall, uninstall, complete removal, upgrade, and unmark are some of the available options for this program.Removal of the program and configuration files is accomplished by ″complete removal,″ whereas removal of the software is accomplished through ″removal.″ It is used when a user identifies a modification (such as tagging a package for removal) and then determines that the change is no longer necessary.
It is possible to click ″Apply″ after the user has indicated that modifications are needed.A program list is updated by scanning the repositories, which may be done by pressing the ″Reload″ button.Using the option ″Indicate Any Upgrades,″ you may mark all newer versions of software that will be used to upgrade the older software that is currently installed.Packages may be sorted into groups by clicking on the buttons located on the bottom left-hand side of the screen.When users choose a group, they may do searches inside the group.
- A few examples of groups are: all, uninstalled (not installed), installed (not installed), development (LP-PPA-noobslab-themes/raring), noted modifications (arch: amd64), and many others (see table below).
- Everything would be included in the term ″all.″ In this case, ″Not Installed″ and ″Installed″ would refer to packages that have not been installed as well as ones that have been installed.
- Software development tools such as Geany or Eclipse would be considered ″development.″ There is a repository called ″LP-PPA-noobslab-themes/raring.″ Those software modifications that the user has made but has not yet implemented are referred to as ″marked modifications.″ AMD64 CPUs are supported by the ″arch: amd64″ software package.
- In addition to these, there are several additional categories and groupings.
- The majority of them are self-explanatory in nature.
- In contrast to a package manager, GDebi is limited to installing local deb files.
You may also use this software to run in a terminal window.Use the GDebi graphical user interface by selecting Open with GDebi from the context menu of a deb file.Then GDebi appears, displaying information about the item it has just downloaded.
- Description, version, necessary files, files contained in the package, and other information are some of the items on the list.
- A user can utilize GDebi to swiftly install a local file when he or she needs to do so quickly.
- In addition, GDebi consumes less RAM and CPU resources throughout the installation process.
- It is not a package manager, as APTonCD claims to be.
- As an alternative, users can create a CD that has all of the Debian files for the program that has been installed on the computer using this software.
- This, however, would only work if the Debian cache had not been cleared previously..
- A directory path to a folder containing debs, such as /var/cache/apt/archives, is an example of a directory path.
This location is where the deb file is downloaded to when a program is installed through the package manager’s download function.They are stored as a backup in case something happens to the main computer.It then burns a disc or builds an ISO file from all of these debs (virtual disc file).
- In this way, administrators can use the disc to install the same software on multiple systems that must be identical to the original system.
- A backup disc for the packages may also be created with this.
- A Debian package manager that is customized for Ubuntu is known as the Ubuntu Software Center (also known as USC).
- Aiming for simplicity, this package manager has been designed.
- In comparison to Synaptic, the Ubuntu Software Center is a more basic application.
- Ubuntu Software Center, on the other hand, was created with mainstream users as a primary focus of development.
- When it comes to the package manager, it’s fairly straightforward.
- There is a list of program kinds to the left of the screen, and popular and new apps to the right and center of the screen, respectively.
All programs and installed applications will be accessible from the top bar, which includes large buttons.Because of its straightforward design, this package manager should be self-explanatory, and users should have no trouble learning how to use it.Apps may be reviewed by other users using this package manager, which is free.Ubuntu users will benefit from this since it will assist them avoid using buggy or dangerous applications.Packet Manager Systems use a list file, which is as follows: System files that are critical for the effective operation of package managers may be found in Debian-based Linux distributions.There is one in particular that consumers need to be aware of, and that is An unformatted plain text file with a list of repositories can be found in the directory /etc/apt/sources.list.
- Packet managers scan this file and utilize the addresses in it to compile a list of packages that may be installed on a computer.
- Beginning with the pound symbol, this file contains commented lines (also known as disregarded lines) ( ).
- Package managers, as well as manually editing this file, can be used to add or remove repositories.
- In order to disable repositories, the pound sign () must be placed at the beginning of the line.
- Below are two examples of line breaks.
- Debsaucy main is a password-protected website.
- Debian Strictly Restricted Debian Strictly Restricted In the above example, binary (compiled) and source code packages are indicated by the two lines indicating that the repositories are available for download.
It is then necessary to provide the address.That information is followed by the operating system version, which indicates which software is compatible with the system.When the word ″saucy″ is entered into the field, the field is considered to be complete.For Ubuntu 13.10, this is the codename.This prevents the installation of applications for Ubuntu 14.04 or Debian (Wheezy) on this system.
- Following that, the repository type is specified (this is used by Ubuntu systems).
- The strings main, main limited (or merely restricted), universe, and multiverse are all valid choices for this field.
- Canonical provides license and support for the software under the conditions outlined here (makers of Ubuntu).
- It is free software, and Canonical provides support for it.
- VLC, Firefox, Thunderbird, and Clementine are just a few of the programs that are available.
- Licensing limitations on this product include prohibitions on distributing, editing, and duplicating, among other things..
Among the helpful apps that Canonical provides are those in this category of software.Many users require MP3 codecs and RAR, for example, yet none of these pieces of software is available as free open-source.Universe – Software downloaded from a PPA (such as Launchpad) or an open-source website (such as Sourceforge) would fall under this category of software.
Despite the fact that this program is free and open-source, Canonical does not provide any technical assistance for it.Noobslab’s icons and themes, for example, are a good illustration of this.This group comprises closed-source software that is subject to licensing limitations and does not receive any support from Canonical.Such software might include Linux video games that are acquired from a third-party firm that is not affiliated with Canonical, as an example of this sort of software.
A free, closed-source program such as Opera, for example, may be included in this group.The term ″non-free″ alludes to the concept of a multiple world.It is possible that users may notice the phrases stable, backports, suggested, updates, and security in addition to the others.In general, this software is intended for widespread usage and is considered stable.
Software in testing – This software is still in the process of being tested before it is made available as part of the next stable release.″Unstable″ means that the program is brand new and is not yet ready to be classified as ″Testing.″ Backports – Backport repositories include changes that are not supported by the Canonical development teams.These updates are being considered for inclusion.
In addition, Canonical supports these upgrades and employs them to ensure that they are stable before distributing them through its software updates repository.These repositories provide generic updates, such as upgrading Firefox from version 33 to version 34, and are categorized as follows: Security – This category of software contains updates that are specifically related to security.
What packages are installed by default in Debian? Is there a term for that set? Why some of those packages are `automatically installed` and some not?
- The Debian distribution includes a subset of packages that are automatically installed. Is there a word for this subset of packages? Because there are packages of various priority levels among the packages installed by default, I speculated that it had something to do with package priorities. However, this does not appear to be the case. Furthermore, several of the packages in the original subset, such as wireless-tools, include an automatically installed flag. As a result, if packages from the first subset that are dependent on them are manually deleted, they will be automatically removed. My question is if the installation tool merely keeps a list of items that should be deemed manually installed and does not automatically install their dependencies. Answers to the first two questions are as follows: Following the installation of the main Debian utilities, the Debian installer seems to use tasksel in order to complete the installation ″tasks.″ Typical tasks include the ″standard″ task and the ″laptop″ task, to name a few. The following is taken from the tasksel page: task that is ″standard″ The standard task is a specific job that is utilized by the Debian Installer to complete its tasks. It is truly dependent on the priority of the items. What exactly falls under the purview of the ″standard system″ task? The aptitude search string tasksel -task-packages standard is equivalent to aptitude search pstandard -prerequisite -F percent p, which is an aptitude search string that translates to aptitude search pstandard, necessary, and important. As a result, tasksel installs the most common, needed, and important packages. ″Laptop″ assignment The laptop task is a specific task used by Debian Installer to pull the packages that are helpful on a laptop. It includes the following packages: The following packages are available: wireless-tools, acpi-support, cpufrequtils, powertop, acpid, apmd, pcmciautils, pm-utils, anacron, avahi-autoipd, bluetooth.

10 Most Used Linux Distributions of All Time
In this article, we will look at the ten most popular Linux distributions, ranking them according to the vast amount of software available, the ease with which they can be installed and used, and the amount of community support available on web forums. That being stated, here is a list of the top ten distributions of all time, presented in descending order.
10. Arch Linux
- Despite the fact that it is not based on any other distribution, Arch Linux is widely recognized and utilized by the Linux community, making it a unique player in the Linux ecosystem.
- Traditionally, Arch has not been advised for new users, mostly due to the fact that the installation procedure is quite hard and will need a significant amount of user participation.
- It is necessary to have a basic understanding of partitions, LVM, and Linux in general in order to complete a successful installation of this software.
- The good news is that this is precisely what provides the user with the ability to personalize the system to his or her specific preferences.
- CentOS (Community ENTerprise Operating System) is a Linux distribution that is most recognized for its server capabilities.
- Although the desktop version is not as popular as the mobile version, it is always improving its aesthetic appeal year after year.
- Despite the fact that it is best known and most often used as a Linux server distribution, its desktop version is always improving.
- Apart from that, CentOS is the number one option to Red Hat Enterprise Linux on cloud VPS suppliers due to its robustness, reliability, and 100 percent binary compatibility with RHEL, among other factors.
- This is arguably one of the most important factors contributing to the continued expansion of this distribution.
- If you ask me, this is my personal preference when it comes to servers.
- Elementary (or, more accurately, Elementary OS), a Linux distribution aimed at Microsoft and Apple customers, is likewise based on the Ubuntu Linux operating system.
- It was first made available in 2011 and is currently on its fifth stable release (codename ″Hera,″ which was released last year), which is based on Ubuntu 18.04.
- It was first made available in 2011 and is currently on its fifth stable release (codename ″Hera,″ which was released last year) is based on Ubuntu 18.04.
- On a personal level, I think this is one of the most visually appealing desktop distributions I’ve ever come across.
- The well-polished visual appearance of Elementary is unquestionably one of the game’s distinctive characteristics.
- We can say that Zorin has risen from the ashes this year, despite the fact that it did not make it onto the list of the Top Linux distributions.
- This Ubuntu-based distribution was created and is still being maintained in Ireland to this day.
- In order to appeal to Windows users, it offers a graphical user interface (GUI) that is comparable to Windows and several programs that are similar to those present in Windows.
- The primary purpose of this distribution is to provide a free operating system that is comparable to Windows while also allowing Windows users to utilize Linux without encountering any difficulties in the process.
- This year saw the introduction of Zorin 16.
- The Fedora Project is responsible for the development and maintenance of Fedora (and sponsored by Red Hat, Inc.).
- Fedora’s greatest defining trait is that it is constantly ahead of the curve when it comes to incorporating new package versions and technologies into its distribution.
- For better or worse, if you want the latest and best free and open source software, Fedora is one of the first places you should start looking.
- A surprising amount of growth was witnessed by Manjaro, an Arch Linux-based distribution, in 2016.
- Without a question, the maintainers of Manjaro have been able to continually provide a pleasant experience for both novice and seasoned Linux users by using the robustness and functionality of Arch Linux.
- Recall that Manjaro comes with preloaded desktop environments, graphical apps (including a software center), and multimedia codecs for playing music and video files if you don’t remember anything else about it.
- In the year 2020, four significant upgrades were released: versions 19.0, 20.0, 20.1, and 20.2 of the operating system.
- Finally, but certainly not least, do yourself a favor and give Manjaro a go.
- OpenSUSE, along with Ubuntu, is one of the cost-free alternatives to the enterprise-class operating system (Red Hat Enterprise Linux).
- Furthermore, according to its developers, OpenSUSE is the operating system of choice for both novice users and geeks alike (you may or may not agree with this, but that is what they say).
- And on top of all of that, the acclaimed and award-winning SUSE Linux Enterprise solutions are built on the OpenSUSE foundation.
- Last year, a new version of openSUSE Leap 15.2 was made available for download.
- Ubuntu is a standout choice for people and businesses who demand expert assistance from the company that created the distribution.
- However, despite the fact that professional assistance is accessible through a support contract, Ubuntu has a big user base, and the community support is also excellent.
- Furthermore, because Ubuntu is available in both desktop and server versions and is based on Debian, it is a rock-solid operating system.
- Ubuntu is available in both desktop and server editions.
- Long-Term Support (LTS) versions are those that will get assured support for a period of five years from the date of its publication.
- In addition, you’ll see on this list that various desktop distributions are built on Ubuntu – which is another factor contributing to the popularity of the operating system.
- Debian, which has been around for more than 27 years in the Linux ecosystem, is known for its resilience, stability, and well-oiled release cycle, among other things.
- In addition, it is the distribution with the greatest number of accessible packages and is one of the most popular alternatives for hosting servers on the internet.
- The current stable release (version 10.9, codename Buster) will be phased out in favor of Debian 11 (codename Bullseye), which will be released around the middle of 2021.
- There are no indications that Debian may revert to the old SysVinit as the default system and process manager in the near future.
1. Linux Mint
- Linux Mint is an Ubuntu-based distribution that is reliable, strong, and visually appealing.
- For example, up to version 20.x, it provided a plethora of helpful applications right out of the box, which contributed to its widespread use (such as multimedia codecs).
- However, with version 18, this was no longer the case, and it is now up to the users to install such packages once the operating system has been successfully installed.
- To be clear, it is not the case that Linux Mint has terminated support for multimedia codecs and other software that was included with the distribution until recently.
- The rationale for this choice is straightforward: delivering codecs did not considerably enhance the distribution, and it required a large amount of labor on the part of the development team.
- It is precisely for this reason that Linux Mint is frequently chosen as the preferred distribution by both new and experienced users alike — it is a comprehensive operating system that is ready for use immediately after installation is completed.
- Throughout this post, we’ve provided you with a succinct overview of the top 10 Linux distributions of all time.
- You may be new to Linux and unsure of which distribution you should start with, or you may be an experienced user looking to explore new possibilities.

What is a Linux Distribution?
- A Linux distribution, often known as a Linux distro, is an operating system that is assembled from components produced by a variety of open source groups and programmers and distributed as a single package.
- Each distribution includes the Linux kernel (which serves as the operating system’s foundation), the GNU shell utilities (which provide the terminal interface and commands), the X server (which provides a graphical desktop environment), the desktop environment, a package management system, an installer, and various other features and services.
- The source code for several components is supplied in source code form since they are produced independently of one another.
- Other software like as the KVM hypervisor and an Internet browser are also included in the distributions, as well as administration tools.
- In a single Linux distribution, hundreds of software packages, utilities, and applications may be available for download.
- Linux distributions are created by compiling code from open source projects and combining it into a single operating system that can be installed and booted from a single source.
- Linux distributions are available for a variety of platforms, including desktop computers, servers without a graphical user interface, supercomputers, mobile devices, and specialized platforms such as home theater PCs and embedded systems, among others.
- Given that Linux is free and open source software, anybody may create their own Linux distribution, either by building it from the source code themselves or by changing an existing one.
- A total of about 300 Linux distributions are being maintained at any given time.
- Fedora (Red Hat), openSUSE (SUSE) and Ubuntu (Canonical Ltd.), for example, are commercially sponsored distributions, whereas Debian, Slackware (Gentoo), Gentoo (Arch Linux), and Arch Linux are wholly community-driven distributions.
Although the vast majority of distributions are ready to use and pre-compiled for a certain instruction set, some distributions are supplied mostly in source code form, which must be generated on the fly during the installation process.A price for support and customer development services is levied by certain commercial distributions on its customers.Open source license does not allow for the collection of fees for open source software.
- Linux is a free and open-source operating system that is widely used across the world.
- Because of its versatility and position as an open-source project, it has spawned a large number of Linux-based distributions with a variety of powerful characteristics.
- When something is open-source, on the other hand, it is frequently the obligation of the user to maintain it.
- It may be difficult to obtain managed customer assistance as a result of this.
