Package removal in Linux (YUM & APT)

• Different forms of package removal in Linux are discussed in detail with illustrations. Remove or remove software packages from your system using the Yum or apt-based systems. A segment of the YUM series, this piece may be found here. Other pieces in this series can be found by clicking on the following hyperlinks: The following topics will be covered: package installation in Linux (YUM & APT)

• and package download in RHEL.

We will be looking at how to remove packages from Linux systems that are based on YUM or APT. Package removal, often known as wiping a package from the system, is another term for this operation.

Package removal on YUM based system

Removing package using yum

YUM-based systems such as Red Hat or CentOS may be configured to uninstall packages by passing the erase or remove argument to the yum command in conjunction with the package name.For example, to uninstall telnet, we will run the commands yum delete telnet and yum remove telnet respectively.The following plugins have been loaded: amazon-id, rhui-lb, search-disabled-repos Putting Dependencies Back Together -> Checking for transactions in progress -> Package telnet.x86 64 1:0.17-60.el7 will be removed from the system -> Completed Dependency Dependencies in the Resolution Resolved ============================================================================================================================================================= packagearchversionrepositorySize ===> packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVersionRepositorySize => packageArchVer telnetx86 641:[email protected] has been removed from the system.

• 1:telnet-0.17-60.el7.x86 641/1:telnet-0.17-60.el7.x86 641/1:telnet-0.17-60.el7.x86 641/1:telnet-0.17-60.el7.x86 641/1:telnet-0.17-60.el7.x86 641/1:telnet-0.17-60.el7.x86 641/1:telnet- telnet.x86 64 1:0.17-60.el7 has been removed from the system.
• Complete!
• Even if you use the yum wipe telnet command, the result will be the same as it is above.

• In order to minimize unintentional deletions, it will publish the package details to be deleted on the screen and ask for approval before deleting.

Removing package using rpm command

Using the rpm command with the erase -e option, the same result may be obtained. rpm -evh telnet Preparing. Organizing and eliminating waste. 1:telnet-1:0.17-60.el7 In the above example, we used the options -e (erase), -v (verbose), and -h (print hash marks) in conjunction with the package name.

Package removal on APT based system

Removing package using apt-get

Use the rpm command in conjunction with the wipe -e option to accomplish the same result:rpm -evh telnet Preparing. Disposal of waste and cleanup 1:telnet-1:0.17-60.el7 To illustrate, we used the -e (erase) and the -v (verbose) options in conjunction with the name of the package in the preceding example (see below).

Removing package using dpkg

This may be accomplished by using the -remove parameter to the dpkg command, which is part of the Debian package management.the command dpkg -remove telnet (Reading database.81678 files and directories currently installed.) Taking telnet out of the equation (0.17-40).

Processing triggers for the man-db database (2.7.5-1).As you can see in the display above, telnet has been removed.Take note of the fact that the dpkg or rpm commands do not prompt the user for confirmation before uninstalling a package.

How to Uninstall Package in Linux

The most recent update was made on August 4, 2020 at 8:39 a.m.Aoife McCambridge contributed to this article.Sometimes we install applications or files and then decide that we don’t want them anymore.

For example, the following terminal command may be used to install a package: sudo apt-get install kubuntu-desktop kubuntu-desktop However, when we use the command ‘rm’ to remove this, we receive the following error message: the following command is executed on the [email protected]:$ sudo rm kubuntu-desktop rm: unable to delete ‘kubuntu-desktop’ from the system:.Using this tutorial, we will demonstrate how to overcome this problem.

Solution

• First and foremost, you must be familiar with the commands apt-get and rm. Apt-get is a command-line tool for managing packages and dependencies. In order for it to be effective, it must be accompanied by a large number of directives.
• In order to uninstall a package, we use the command apt-get: sudo => to perform the action as an administrator
• apt-get => request that apt-get be executed
• remove => remove
• kubuntu-desktop => the package to be removed sudo apt-get remove kubuntu-desktop

Rm is a command that is used to remove files or directories from your computer. For example, if I wish to delete the test.txt file that is located at the root of my personal file, I would use the following command: rm /home/username/test.txt

Rm -r /home/username/xxx is the command to use to delete the xxx file in the same location.

How to Easily Remove Packages Installed From Source in Linux

Under one of our earlier posts, we demonstrated how to install and remove applications in Linux using methods other than the standard package managers.In that article, we also learned that well-constructed software has an uninstaller that is easy to use.You will be able to uninstall the packages just as easy as you may install them in this manner.

The truth is, however, that is not always the case.Despite the fact that there are many packages out in the world that are difficult to remove cleanly, At times, you have no option but to utilize a program like this since you require the capabilities it provides.There is, however, a solution to the issue at hand.

• In this post, we’ll teach you how to use the program ″stow″ to quickly and efficiently delete packages that have been installed on your Linux system.

Step 1: Install Stow

″stow″ should be available in your standard package repositories, if you haven’t already.Because we are using CentOS in this example, we will require the enhanced EPEL libraries.You may put them in place by running the following command: yum install epel-release is the command to use.

After that, install stow in the following manner: yum stow the installation To confirm the installation, select Yes from the drop-down menu: The location of our package files must now be determined after stow has been successfully installed.

Step 2: Choose Where to Store Package Files

The standard ″make install″ program transfers the package files to a number of different locations around the system.Stow works by storing all of the files in a single directory and then constructing symlinks to the locations where the files should have been stored initially, according to the documentation.As a result, we must specify a directory in which stow will store all of the package files.

This is often found in the directory /usr/local/stow/.Additionally, in this location, we have a separate directory for each of the packages we are using.So, for example, if we wish to install the ″hello″ program that we used as an example in the previous article, the files will be kept in the following directory: /usr/local/stow/hello.

• However, the place might be anywhere.
• We’ll be saving the files in the following directory: /home/bhagwad/stow for the sake of demonstration:

Step 3: Using “make install”  with the “prefix” Option

It was previously discussed that the following commands are required when installing from the source code: ./configure create a make an installation To install using stow, we just alter the last step to read as follows: install prefix=/home/testuser/stow/hello in make install Using the ″prefix″ option, we can direct the packages to be placed at the specified location.This location is nothing more than the directory that was selected in Step 2 with the package name appended as a new folder within it.When you do this, the files will be installed at the place you specify, as seen here: Now that we have all of the files necessary for the package in a folder in the stow directory, we can begin building the package.

It is now time for the magic to happen!

Step 4: Completing the Installation with stow

First, ″cd″ into the stow directory as follows to begin the installation process: cd /home/testuser/stow /home/testuser Please make sure that the folder containing the files is located only one directory below your current directory.Now type the following: stow hello That’s all there is to it!The software has been successfully installed on your system.

A snapshot of the ″hello″ command being used as intended is shown below: But hold on a sec.The true advantage will not be realized till later.Uninstallation.

Step 5: Removing Packages

It is the fact that it is so simple to remove packets from the system that makes stow so appealing.There is no requirement to retain the source packages or anything like that.As in Step 4, just browse to the stow directory and type: stow -delete hello to remove the file.

And now it’s finished!You can see in the example below that the command is no longer functional following this step: The package has been totally erased from the system, according to the system!It’s important to keep in mind that the data haven’t truly disappeared.

• They’re still listed in the ″hello″ directory, which is appropriate.
• You could just as easily reinstall the package using the stow command if you wanted to.
• If you no longer require the files, you may simply remove the ″hello″ folder, and your system will be completely clean!

• We recommend that you use stow every time you install a package from the source code repository.
• It is not worth the risk of having a poorly built package infect your system with files that are difficult to delete once they have been installed.
• All of the symlinks are neatly stored in a single place, and Stow maintains track of which ones have been created and which have been deleted.
• I think it’s an excellent option!
• You do not have to delete packages installed from source if you are a subscriber of our Managed VPS hosting service; simply ask our administrators to do so and sit back and enjoy your time off.

Our administrators will take care of this right away.Thanks for reading this post about how to quickly delete programs loaded from source in Linux.Please share it with your friends on social media using the links provided below, or just leave a note in the comments below.Thanks.

How to Remove Unused Packages in Linux

When we install a package or program in Linux, it also installs a large number of dependencies that are required by the package or software.When we uninstall or delete this program from our Linux system, these packages are always left behind as a result of the process.Over time, our system becomes clogged with these orphaned packages, which take up a significant amount of hard drive space.

As a result, it is recommended that you delete unneeded packages from your Linux system on a regular basis.Unused packages may be found and deleted using a variety of third-party applications available for download online.A number of methods for removing unneeded packages from Linux will be discussed in this article.

• It is possible to eliminate unnecessary packages from Ubuntu/Debian as well as RHEL/Fedora/CentOS systems by following the instructions outlined below.

How to Remove Unused Packages in Linux

Here is a list of the many tools available for uninstalling unneeded packages in Linux.

1. Using Deborphan

In Ubuntu/Debian systems, Deborphan is a command-line program that allows you to locate uninstalled packages that are no longer needed.Here is the command you run in order to install it.apt-get install deborphan $ sudo apt-get install deborphan After it has been installed, you may start it by typing the following command.

deborphan is a dollar amount.It will compile a list of all unneeded packages.openoffice.org-hyphenation myspell-en-gb rhythmbox-plugin-magnatune libgnutls-openssl27 myspell-en-gb rhythmbox-plugin-magnatune libgnutls-openssl27 Using the following command, you may uninstall these packages from your computer.

• orphaner – sudo orphaner It will open a window and provide a list of all unwanted packages, which you can pick and then press the OK button to have them deleted.

2. Using Gtkorphan

Gtkorphan is a graphical program that allows you to pick and uninstall unnecessary packages from your Linux installation through the command line.In order to use it, a Linux system with a desktop environment must be used; it is not a command-line tool.If your Linux system does not have a desktop environment, Deborphan can be used instead.

The command to use in order to install Gtkorphan is provided below.gtkorphan can be installed using sudo apt-get install gtkorphan Gtkorphan may be started by using the following command after it has been installed.the command sudo gtkorphan It will display the following type of window, which will list all of the orphan packages in the libs area.

• If you wish to see orphan packages in all folders, just choose the checkbox labeled ‘Show all orphan packages’ from the drop-down menu.
• Take your time and read over the list.
• If you wish to keep a package, right-click on its name and pick the ‘Hibernate Package’ option from the context menu.

• If, on the other hand, you wish to uninstall a package, just right-click on its name and pick ‘Select for removal’ from the context menu.
• Once you have finished going through the list, click Ok to delete any programs that are no longer needed.

3. Using autoclean & autoremove

You may also use the following command to uninstall all of the packages that are no longer needed at the same time. —suspend —suspend —suspend —suspend —suspend —suspend It will not, however, request any confirmation or provide any information about the shipment. Simple as that, it will discover and delete any unneeded packages from your Linux system.

4. Using Rpmorphan

Rpmorphan is a command-line application that works in a similar way to Deborphan in that it finds and removes unwanted packages in RHEL/Fedora/CentOS Linux.Here is the command you run in order to install it.First and foremost, we must install the perl and perl-tk packages.

yum perl perl-Tk install perl perl-Tk Then, using this URL, get the RPM package for it.For the sake of this demonstration, we have downloaded version 1.16.Installing it is as simple as running the following line.

• rpm -Uvh rpmorphan-1.16-1.noarch.rpm rpm -Uvh rpmorphan-1.16-1.noarch.rpm Once it has been successfully installed, use the following command to see a list of unneeded packages.
• rpmorphan It works in a similar way as deborphan in that it will show all unneeded packages.
• The install-time option may be used to display orphaned packages that were installed more than a few days ago, as illustrated in the following code snippet.

• 2 rpmorphan -all -2 install-time Rpmorphan -all Similar to this, if you want to see all useless packages that haven’t been used in the previous two days, you may use the access-time option.
• access-time 2 is the default value for the rpmorphan command.
• Once you have a list of the packages you want to delete, you can use the rm command to get rid of them.
• That’s all there is to it.
• On this post, we learned about four distinct methods for locating and removing unneeded packages in Linux systems.

Uses of RPM

• RPM may be used to do the following tasks: install packaged software
• upgrade packaged software
• delete package software
• query comprehensive information about installed packaged software
• validate the integrity of packaged software and the resultant software installation
• and

The utility only works with packages that have been generated specifically for processing by the rpm package and have the a.rpm extension. (Please keep in mind that the use of RPM to create software is outside the scope of this tutorial.

RPM Commands

The following is the basic format of a rpm command: rpm -option

RPM Options

option	Meaning
-i	install a package
-v	tells the rpm command to print out verbose (detailed) information as the command runs.
-U	upgrade a package
-qa	query all installed packages
-qa -last	all recently installed packages
-e	remove a package
-nodeps	install, upgrade or remove a package without checking for dependencies
-h	Print 50 hash marks as the package archive is unpacked – hash marks get printed out to assure the installer that the RPM is working, and if it is, how far along it is.
-test	tells the rpm command to test the installation or upgrade process but not to install the file
-Vp	verify a package

The options can be combined in a way that looks like -ivh.

Installation and Upgrades

• The following command completes the installation. the rpm -ivh php55-5.5.10-1.el6.x86 64.rpm command is used to install php55-5.5.10-1.el6.x86 64.rpm The following command installs the package without first determining whether or not it has any dependencies. This may have an influence on the software’s ability to function correctly. rpm -ivh php55-5.5.10-1.el6.x86 64.rpm -nodeps In addition, when the rpm install or upgrade command is executed, it performs the following tasks: it checks for errors in the package and the files that need to be installed
• it performs pre-installation tasks
• it uncompresses and places the files in the appropriate locations
• and it updates both the RPM database and the RPM file system.

Package Dependencies

RPM packages frequently have dependencies on other RPM packages.This indicates that the installation of one package is contingent on the existence of another package.You can check for package dependencies before installing them by running the following command: prior to installing a package, run the following command: rpm -i -test php55-5.5.10-1.el6.x86 64.rpm php55-5.5.10-1.el6.x86 64.rpm This is an example of a dependency that has failed:

Package Upgrades

The following command replaces the previously installed PHP with php55-5.5.10-1.el6.x86 64.rpm: rpm php55-5.5.10-1.el6.x86 64.rpm -Uvh php55-5.5.10-1.el6.x86 64.rpm php55-5.5.10-1.el6.x86 64

Package Removal

Rpm -e php55-5.5.10-1.el6.x86 64.rpm is the command that will delete php55-5.5.10-1.el6.x86 64.rpm from your computer. The following command removes php55-5.5.10-1.el6.x86 64.rpm from the system without first checking for dependency problems. rpm -e -nodeps ″php55-5.5.10-1.el6.x86 64.rpm″ -nodeps ″php55-5.5.10-1.el6.x86 64.rpm″

How to Remove Package on Ubuntu From Command Line

Dpkg (Debian Package) is a package manager that is included with various Linux distributions.In order to uninstall a package using the dpkg command, you must first determine what package you want to uninstall by looking up its specific name in the package list.To see a list of the packages that have been installed on Ubuntu, type the following into a terminal window: list of packages installed by sudo dpkg This command displays a list of all of the software, however the list may be excessively large and unhelpful in some cases.

To make a list simpler to navigate, include the following elements: command-line switch sudo dpkg-query –l |less If you already know the name of the product you wish to uninstall, you may search for it by typing it into the search box: grep package name |sudo dpkg–query –l |

• grep package name Replace package name with the phrase you’re looking for in the search bar.
• If you don’t know the whole name, you can indicate a portion of it by encircling it with asterisks (*), like in the following example: sudo dpkg–query –l |
• grep *partial name* sudo dpkg–query –l We recommend that you copy the precise software package name (by right-clicking and selecting ″copy″) so that you may use it later in the uninstallation procedure.

• It is not advised to delete software packages from your computer using the dpkg command.
• The most suggested solution is to utilize a package manager that will automatically remove all dependencies for you.
• While dpkg may successfully delete the requested package, all of its dependencies will remain on the system and may no longer work properly.

Apt-Get Remove Command

In order to uninstall a specific package, run the following command: sudo apt-get delete package name If you use this command, it will request apt to search all the installed apps and attempt to delete or fix those that are not working properly.

Apt-Get Purge Command

In this case, package name should be substituted with the actual package name generated by apt or dpkg. It is simply the program that is deleted by the uninstall command, not the configuration files. Use the purge command to delete the software and configuration files: sudo apt-get remove ––purge package name package name

Clean Command

Additionally, the apt package manager can clean up your system.Enter the command sudo apt-get clean to clear the cache of old/outdated packages from your system.Some apps are installed with dependencies in order to function properly.

These are additional software packages that the application need in order to function properly.While it’s possible to remove an application while keeping all of its dependencies on your system, this is not recommended.If you use this command, it will request apt to search all the installed apps and attempt to delete or fix any that are not functioning properly.

AutoRemove Command

The autoremove command of the apt package management may be used to remove orphaned or unneeded dependencies: apt-get autoremove sudo apt-get With the command: apt-get repair, you can attempt to fix any failed installs, broken dependencies, or corrupted package files that you may have.install using sudo apt-get –f If you use this command, it will request apt to search all the installed apps and attempt to delete or fix any that are not functioning properly.Conclusion You should now have a solid grasp of the many methods available for finding and removing packages on Ubuntu Linux.

How to Uninstall Applications from Ubuntu [Beginner’s Guide]

• Use a program that you don’t use any longer? Take it out. It is true that uninstalling apps is one of the most straightforward methods of freeing up disk space on Ubuntu and keeping your system clean. The many methods of removing applications from Ubuntu will be demonstrated in this beginner’s guide. Is it true that I said numerous ways? Yes, since there are a variety of methods for installing and uninstalling software in Ubuntu, as well as a variety of methods for deleting them. Users of Ubuntu Desktop will be taught how to remove apps via the Ubuntu Software Center (for desktop users), how to remove applications using the apt remove command, and how to remove snap applications from the command line (for intermediate to expert users).

Let’s go over each of these processes one by one.

Method 1: Remove applications using Ubuntu Software Center

Start the Software Center program from your computer’s desktop.You should be able to locate it on the dock on the left side of the screen or by searching for it in the menu.The Installed tab contains a list of all of the programs that have been installed.

If you don’t find a program you’re looking for, try searching for it using the search option.When you access a previously installed program, you should be presented with the option to uninstall it.Simply click on it.

• It will prompt you to enter your account password.
• Input the code, and the programs will be uninstalled in seconds.
• This approach works rather well, with the exception of when Software Center is acting erratically (which it does quite frequently), or when the application in question is a software library or some other command-line utility.

• In such situations, you may always turn to the terminal for assistance.

Method 2: Remove programs from Ubuntu using command line

You are aware that you can install software using the apt-get install or apt install commands.It is not necessary to use the apt-get uninstall command for uninstalling, but rather the apt-get remove or apt remove commands.The command must be used in the following manner to accomplish this: sudo apt uninstall program name removes a program from your computer.

You’ll be prompted to enter your user name and password.When you first enter it, there is nothing visible on the computer screen.That is very natural.

• Simply type it in blindly and hit the enter key.
• The software will not be uninstalled on the spot.
• It is necessary for you to confirm it.

• Enter or hit the Y key when it asks you to confirm your decision.
• Always keep in mind that you must give the correct package name in the apt delete command, or else the command will return an error saying that it was unable to locate a package.
• Don’t be concerned if you can’t recall the actual name of the software.
• You may make advantage of the extremely convenient tab completion feature.
• It’s one of the most useful Linux command-line techniques that you should be familiar with at all times.

What you may do is input the first few characters of the software that you want to remove into the search box on your computer.After that, press the tab key.That command will display all of the installed packages that have those letters at the beginning of their names in alphabetical order.When you locate the required package, you may delete it by typing its whole name into the search box.What happens if you don’t know the precise package name or even the first few letters of the name?You may, of course, display all of the packages that are currently installed in Ubuntu and then grep with whatever string comes to mind.

Using the command below, for example, will display all of the installed packages that contain the string’my’ anywhere in their names, not only at the beginning.the command apt list -installed |the command grep -i my Isn’t that great?I mean, it is.When using the delete command in Ubuntu, make sure to use the package name as a guideline.

Tip: Using apt purge for removing package (advanced users)

Ubuntu removes packages by removing the bundled data, however it may leave behind minor, updated user configuration files if the item was deleted accidentally.This is done on purpose since if you reinstall the same software, it will utilize the configuration files from the previous installation.Use the apt purge command if you want to totally remove it from your system.

You may use it in place of the apt remove command, or you can use it after you have ran the apt remove command.sudo apt purge program name program name Take note that the purge command will not erase any data or configuration files that are stored in the home directory of the user who is running the command.

Method 3: Uninstall Snap applications in Ubuntu

The procedure described above is compatible with DEB packages that have been installed using the apt command, the software center, or straight from the deb file.Snap is a new packaging technique for Ubuntu that was introduced recently.It is in this Snap package format that you will discover the vast majority of the applications available through the Ubuntu Software Center.

Using the Ubuntu Software Center, you can uninstall these apps quickly and efficiently; but, if you prefer to utilize the command line, follow the steps below.To obtain the package name, you must first list all of the snap programs that have been installed.a list in a snap Now, to uninstall the application from Ubuntu, type the package name into the search box.

• Before being removed, you will not be required to authenticate your identity.
• snap remove package name sudo snap remove package name

Bonus Tip: Clean up your system with one magical command

Alright!You’ve learnt how to uninstall the programs.Now, allow me to tell you about a simple command that cleans away residual package traces such as dependencies that are no longer needed and old Linux kernel headers that will not be utilized in the near future.

Simply type the following command into the terminal: apt autoremove sudo apt autoremove A few hundred megabytes of disk space may be readily freed up using this command, which is completely risk-free.

Conclusion

You now know three different methods for uninstalling apps from Ubuntu Linux. I covered both graphical user interface (GUI) and command line approaches to ensure that you are aware of all of your possibilities. It is my hope that you would find this brief guide to be helpful as a new Ubuntu user. Please feel free to contact us with any questions or recommendations.

How to install software from the Linux command line

For anyone who has used Linux for any length of time, they will quickly discover that there are several alternative ways to do the same task.For example, installing software on a Linux computer through the command line is covered in this section.Despite the fact that I’ve been a Linux user for almost 25 years, I still find myself returning to the command line to install my applications time and again.

Installation of applications via the command line often takes place through software repositories (a location where software is stored) and the use of a package manager, which is short for package manager.Packages, which are nothing more than a collection of files connected with a package management system, are used to distribute all Linux applications.Every Linux distribution has a package management system, but not all package management systems are created equal.

What is a package management system?

Installation, updating, and uninstalling Linux applications is accomplished through the use of a package management system, which is made up of sets of tools and file formats that work together.The most widely used package management systems are those developed by Red Hat and Debian.Red Hat, CentOS, and Fedora are all based on the rpm package management system (.rpm files), whereas Debian, Ubuntu, Mint, and Ubuntu are based on the dpkg package management system (.deb files).

Gentoo Linux makes use of a mechanism known as Portage, whereas Arch Linux relies solely on tarballs (.tar files).The fundamental distinction between these platforms is the manner in which programs are installed and maintained.You may be asking what exactly is contained within an.rpm,.deb, or.tar file.

• The fact that all are nothing more than plain old archive files (like.zip) that include an application’s code, installation instructions, dependencies (what other programs it may be dependent on), and the location where its configuration files should be stored may surprise you.
• A package manager is a piece of software that reads and executes all of the instructions in a given package.

Debian, Ubuntu, Mint, and others

Debian, Ubuntu, Mint, and other Debian-based distributions all make use of.deb files and the dpkg package management system, which are both developed by Canonical Inc.There are two methods for installing applications using this system.You may install applications from a repository using the apt program, or you can install applications from.deb files using the dpkg application.

Let’s look at how to do both tasks.Installing applications using the apt package manager is as simple as: sudo apt install app name $ sudo apt install app name It is also quite simple to uninstall a program using the apt package manager: Remove the app name using sudo apt remove.You’ll need to update the app repository first before you can upgrade any of your installed apps: $ sudo apt-get upgrade After that, you may perform the following actions to update any applications that require it: $ sudo apt-get update What if you simply want to update a single application?

• It’s not an issue.
• sudo apt update app name $ sudo apt update app name Finally, suppose the application you wish to install isn’t accessible in the Debian repository, but it is available as an a.deb file download from somewhere else.
• You may manually install it using dpkg, which is a mechanism that apt assists in managing: dpkg -i app name.deb sudo dpkg -i app name.deb

RHEL, CentOS, Fedora, Mageia, and OpenMandriva

Red Hat, its upstream project Fedora, and its ″midstream″ project CentOS all make use of the dnf package manager, which is developed by the company.It has its own syntax, and it serves as a front-end to the RPM distribution system.Dnf and apt are comparable in the sense that the mechanics and aims are the same, despite the fact that their syntax is different.

The Mageia and OpenMandriva distributions, which previously relied only on urpmi for package management, now incorporate dnf as part of their package management infrastructure.The dnf package management replaces the yum command, which was previously available.In order to avoid breaking custom scripts that have been on users’ systems for more than a decade, yum and dnf are now interchangeable (in fact, yum is now built on the same code base as the original version of dnf.) Users should consider upgrading to the latest version of their distribution’s package manager.

• To install an application, follow these steps: sudo dnf install app name app name It’s just as simple to get rid of any unwanted programs.
• dnf uninstall app name with sudo dnf Apps that need to be updated: dnf upgrade -refresh may be found at $ sudo dnf upgrade -refresh In the RPM packaging system, the dnf (also known as yum) command serves as a front-end.
• If you are unable to locate an application in your software repository but are able to download it straight from the vendor’s website, you can manually install an.rpm file using the dnf command.

• $ sudo dnf install./app name.rpm /app name.rpm In this example, you can see that installing, removing, and upgrading Linux applications via the command line isn’t difficult at all.
• You may even find that it is faster than utilizing desktop GUI-based management tools once you become used to it.
• The Debian Apt website, Yum cheat sheet, and DNF wiki are all excellent resources for learning how to install applications from the command line.

How to put Windows back on HDD Starting with Ubuntu only

According to the query, there appears to be no Windows installed on the OP’s hard disk. The most, if not all, of the solutions above are contingent on Windows being installed. Listed below are two techniques for installing Windows using simply an Ubuntu installation or a Live USB drive.

Installing Windows using mkusb-plug

• Installing mkusb: Is it possible to install mkusb using an Ubuntu live USB? It is compatible with both internal Ubuntu disks and live Ubuntu USB devices.
• To begin, click on the mkusb-plug icon and then follow the steps below:

First, we’ll go over the first two steps. Then, we’ll go over the third and fourth. Then, we’ll go over the fifth and sixth steps. Then, we’ll go over the seventh and eighth steps. Then, we’ll go over the ninth and tenth steps. Hopefully, you now have a Windows USB installer ready to infect your PC with.

Installing Windows 10 without USB using Ubuntu GRUB

• Make a backup of the target drive.
• Extraction of the Windows ISO to a 6GB NTFS partition on the hard disk.
• Create an NTFS partition on your hard disk that is at least 20GB in size for the Windows installation.
• Open Disks (Gnome-Disks) and make a note of the Device (/dev/sdx), as well as the UUID of the Windows ISO extraction partition.
• Copy the following menuentry to /etc/grub.d/40-custom/* in order to support the msdos partition table:

• ‘Windows Recovery Environment (on /dev/sda4)’ is a menu entry with the classes windows and operating system. When the $menuentry id option is ‘osprober-chain-592C85254E2CD0B7’, insmod part msdos and insmod ntfs are both specified, the root value is hd0,msdos4. If the value is true, search for -no-floppy and -fs-uuid and change the root value to ‘hd0,msd otherwise search -no-floppy -fs-uuid -set=root 592C85254E2CD0B7 -no-floppy -fs-uuid -set=root parttool $ hidden-drivemap -s (hd0) $ chainloader +1 ntldr /bootmgr /parttool $ hidden-drivemap -s (hd0) Step 4: Modify the menuentry by changing sda4 to sdax, microsoftdos4 to microsoftdosx (4 places), and 592C85254E2CD0B7 to UUID, in that order.
• Run sudo update grub to ensure that the ntldr /bootmgr entry in grub.cfg is correct.
• Boot the machine into the newly generated Windows menu entry and follow the on-screen instructions to install Windows on the newly created partition.
• It will be possible to reinstall Ubuntu since the GRUB bootloader will have been replaced with the Windows bootloader.

Add the following menuentry to the /etc/grub.d/40-custom/ directory for the GPT partition table: menuentry ‘Windows Recovery Environment (on /dev/sdc1)’ with the windows and operating system classes set to ″Windows″ and ″OS.″ $menuentry id option ‘osprober-chain-5642BC722509341F’ is a menu entry id option.part gpt insmod part gpt insmod part gpt insmod part gpt If insmod ntfs set root=’hd0,gpt1′ is true, then search -no-floppy -fs-uuid -set=root -hint-bios=hd0,gpt1 -hint-efi=hd0,gpt1 -hint-baremetal=ahci0,gpt15642BC722509341F is true, then search a if not, search -no-floppy -fs-uuid -set=root 5642BC722509341F 5642BC722509341F fi drivemap -s (hd0) $ chainloader +1 ntldr /bootmgr fi drivemap -s (hd0) $ chainloader +1 ntldr /bootmgr fi drivemap -s (hd0) This approach may be be modified in order to create a Windows installer USB or to include a Windows installer in a multiboot USB drive, for example.Limitations Partition tables and boot modes are restricted in Windows 10 due to technical restrictions.

A device with an MSDOS partition table was capable of hosting a Legacy mode Windows installation.I was able to successfully install Windows in UEFI mode on a device that had a GPT partition table.It was not possible for me to install Legacy mode Windows on a device that had a GPT partition table.

• I was unable to install UEFI mode Windows on a disc that had a GPT partition table, nor was I able to install Legacy mode Ubuntu.
• There may be workarounds that aren’t included in this answer, so please keep that in mind.

Uninstalling Packages With Apt Package Manager

In this module, we will learn how to remove packages from our Debian/Ubuntu systems using the apt package manager.

Find The Package You Want To Uninstall

First and foremost, we must locate the package from which we wish to remove its components.With the following, we can quickly and easily identify the actual name of our package: $ dpkg -list |grep ″disabled″ This aids us in locating the specific product that we will require for the subsequent phases in the process.

Once we have discovered the package th
