    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

    1. Start the Software Center program from your computer’s desktop.
    2. 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.
    3. The Installed tab contains a list of all of the programs that have been installed.
    4. If you don’t find a program you’re looking for, try searching for it using the search option.
    5. When you access a previously installed program, you should be presented with the option to uninstall it.
    6. 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

    1. You are aware that you can install software using the apt-get install or apt install commands.
    2. It is not necessary to use the apt-get uninstall command for uninstalling, but rather the apt-get remove or apt remove commands.
    3. The command must be used in the following manner to accomplish this: sudo apt uninstall program name removes a program from your computer.
    4. You’ll be prompted to enter your user name and password.
    5. When you first enter it, there is nothing visible on the computer screen.
    6. 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)

    1. Ubuntu removes packages by removing the bundled data, however it may leave behind minor, updated user configuration files if the item was deleted accidentally.
    2. This is done on purpose since if you reinstall the same software, it will utilize the configuration files from the previous installation.
    3. Use the apt purge command if you want to totally remove it from your system.
    4. You may use it in place of the apt remove command, or you can use it after you have ran the apt remove command.
    5. 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.

    2. Snap is a new packaging technique for Ubuntu that was introduced recently.
    3. It is in this Snap package format that you will discover the vast majority of the applications available through the Ubuntu Software Center.
    4. 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.
    5. To obtain the package name, you must first list all of the snap programs that have been installed.
    6. a list in a snap Now, to uninstall the application from Ubuntu, type the package name into the search box.

    3. 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.
    4. 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.

    Unlike dpkg, which may be run from a script without the use of the ″ -y ″ option, apt requires the usage of the ″ -y ″ switch in order to prevent human input. As a result, apt could automatically resolve package dependencies and delete packages that are not associated with the target specified by the command.

    apt:

    1. It is important to note that when I delete iptables (I use firewalld), lxd and ufw (which is a front-end for iptables) are also removed.
    2. But what if I didn’t want lxd to be deleted from my system?
    3. Well, it’s no longer there: purge iptables with apt-get -y Taking a look at the package listings.
    4. Done Constructing a dependency tree Reading the current situation of affairs.
    5. Done Following packages will be REMOVED from the system: Ubuntu-standard* ufw* lxd* iptables* lxd* ubuntu-standard* ufw* 0 packages were upgraded, 0 were freshly installed, 4 were removed, and 54 were not upgraded.
    6. Following this process, 23.2 MB of disk space will be made available.
    • (Reading the database; there are presently 90906 files and folders installed.) Ubuntu-standard is being deprecated (1.417.3).
    • Taking away the ufw (0.36-0ubuntu0.18.04.1).
    • ufw is a firewall that does not need to be stopped (not enabled) lxd (3.0.3-0ubuntu1-18.04.1) has been removed.
    • Dnsmasq configuration for LXD has been removed.

    1. Note Because dpkg prevents me from possibly affecting the system in an unanticipated way if I were to use it in a programmed execution, and because it refuses to uninstall both ufw and lxd, I have the following problem: dpkg -r iptables is a command that allows you to install an IPtables configuration.
    2. dpkg: There are dependency issues.
    3. prevent the removal of the iptables configuration: lxd is reliant on the iptables system.
    4. ufw is reliant on the iptables package.
    5. dpkg: package for handling errors on the command line iptables (-remove): dependency difficulties preventing it from being removed During the processing, the following errors were encountered: iptables

    Conclusion:

    Because of this, even while we prefer for our scripts to succeed instead of failing, it is possible that a script may fail rather than succeed because it will affect the system that is not the goal of the command, which may be advantageous in some cases. As a result of this use-case, dpkg -r could be more preferable for programmed execution.

    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

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

    Uninstalling Packages With Apt

    • When it comes to removing packages using the apt package manager, we have two options: the first is to use the apt package management’s uninstall command, which is as follows: remove
    • \sPurge

    1. Using apt remove

    To uninstall a package using the’remove’ command, enter the following command: $ sudo apt remove

    2. Using apt purge

    With the ‘purge’ command, we may quickly and efficiently remove packages from our system as follows: $ sudo apt-get remove

    What’s the difference between ‘remove‘ and ‘purge‘?

    1. So the obvious question is when to use the terms ″remove″ and ″purge,″ and how do you know when to use them?
    2. The key difference between’remove’ and ‘purge’ is that’remove’ simply gets rid of the package, leaving any configuration files intact, but ‘purge’ gets rid of the package and all of its configuration files.
    3. ‘purge’, on the other hand, not only removes the package, but it also removes all configuration files that are located outside of the home directory.

    A Fun Little Secret

    Contradictory to their primary use, both ‘purge’ and’remove’ may be used to INSTALL packages, which is somewhat contrary to their primary function. As an example, the following package name might be created by attaching a ‘+’ to the end of it: $ sudo apt-get install

    Post Uninstall Clean Up

    The removal/purging of our package has been completed successfully at this point.As a matter of good practice, we can now run some commands to clean up after the removal has been completed.We may erase the cache of the old/outdated packages by using the following command: We can uninstall packages that are no longer necessary by using the following command: Finally, any failed or broken installations can be repaired using the following procedure:

    Conclusion

    As a result, we learned how to quickly and efficiently remove packages from a Debian/Ubuntu-based system by utilizing the apt package management system.

    In order to install programs on Ubuntu, you’ll need to log in with your username and password.Is there anything that could be simpler?I seriously doubt it.Tip: As I said in the post ″Things to Do Once Installing Ubuntu 16.04,″ you should activate the Canonical partner repository after you have completed the installation.

    By default, Ubuntu only distributes software that is downloaded through the Ubuntu Software Repository (verified by Ubuntu).However, there is also a Canonical Partner repository, which is not directly managed by Ubuntu and contains commercial software that is not open-source or free.Allowing access to this repository offers you access to a greater variety of software.This solution will allow you to install Skype on Ubuntu without a hitch.

    • Look for the Software & Updates option in the Unity Dash.
    • Check out the possibilities for Canonical Partners under the Other Software category in this section as well.

    1.2 Remove software using Ubuntu Software Center

    Recently, we looked at the Ubuntu Applications Center and how to install software from it.So, what if you used this way to uninstall software that you already installed?The procedure of uninstalling software through the Ubuntu Software Center is as simple as the process of installing it.Open the Software Center and select the Installed option from the drop-down menu.It will provide a list of all the software that has been installed.

    1. Alternatively, you may search for the program by its name directly on the web.
    2. To uninstall a program from Ubuntu, just select it and press the Remove button.
    3. You’ll be required to enter your password one again here.

    2.1 Install software on Ubuntu using.deb files

    • Recently, we looked at the Ubuntu Software Center and how to install programs from it. Have you considered utilizing this approach to uninstall software that you already installed? Installation and uninstallation of software through the Ubuntu Software Center are both simple and straight-forward. Open the Software Center and select the Installed tab from the left-hand navigation bar. All of the software that has been installed will be shown by this utility. Alternatively, you may simply search for the application by its name on the internet. Select the Remove option to completely remove the program from Ubuntu. This is another place where you will be required to enter your password.

    2.2 Remove software that was installed using.deb

    The procedure for uninstalling software that was installed from an a.deb file is the same as the procedure described previously in section 1.2.To remove a program, just navigate to the Ubuntu Software Center, search for the application’s name, and click on the Remove button.You may also use the Synaptic Package Manager as an alternative.Although this is not frequently the case, it is possible that the installed program is not displayed in the Ubuntu Software Center when it is installed.The Synaptic Package Manager displays a list of all the software that is currently available for your system, as well as a list of all the software that is already installed on your system.

    1. It is an extremely powerful and really helpful tool.
    2. Synaptic was the default program for installing and uninstalling software on Ubuntu before the Ubuntu Software Center was created to provide a more user-friendly approach to software installation.
    3. The Ubuntu Software Center was created to provide a more user-friendly approach to software installation.
    4. You may download and install Synaptic Package Manager by visiting the URL provided below (it will open the Ubuntu Software Center).

    3.1 Install software on Ubuntu using apt commands

    Some websites may have directed you to a command such as ″sudo apt-get install″ to install software on Ubuntu, which you may have seen elsewhere.What we’ve just seen is the command-line equivalent of what we saw in Section 1.Essentially, you are utilizing the command-line interface to interact with the Ubuntu Software Center, rather than the graphical interface.Nothing else is different.Installing software with the apt-get command is a simple and straightforward process.

    1. Simply use a program such as sudo apt-get install package name to complete the task at hand.
    2. In this case, sudo grants you ″admin″ or ″root″ capabilities (in the Linux nomenclature).
    3. You can replace package name with the name of the program that you want to install.
    4. Auto-completion is included in the apt-get instructions, so if you input a few characters and then click tab, it will show all of the apps that match those letters.

    3.2 Remove software on Ubuntu using apt commands

    It is simple to uninstall software that has been installed using the Ubuntu Software Center, using the apt command, or by using an a.deb file from the command line.The following command will take care of everything; simply replace package name with the name of the program you wish to remove.apt-get uninstall package name sudo apt-get remove package name By hitting the tab key again, you may take advantage of auto-completion once again.Using the apt-get command line is not difficult at all.It is, in fact, really handy.

    1. With these easy commands, you may become more familiar with the command-line interface of Ubuntu Linux, which will be beneficial in the long term.
    2. If you want to learn more about apt-get, I recommend that you read my in-depth explanation on how to use it.

    4.1 Install applications on Ubuntu using a PPA

    Personal Package Archive (PPA) is an abbreviation for Personal Package Archive.Ubuntu users may get their software using this way, which is another approach used by developers to make their product available to them.You came across the phrase ″repository″ in Section 1 of this document.A repository is essentially a collection of software that has been gathered together.Ubuntu’s official repository contains applications that have been reviewed and authorized by the Ubuntu community.

    1. The Canonical partner repository contains software developed by Canonical’s strategic partners.
    2. An APT repository is similar to a PPA in that it allows a developer to build their own APT repository.
    3. Adding a repository to the system by an end user (in this case, you) (sources.list is amended to include this item) makes software offered by the developer in his/her repository available to the user.
    4. You might be wondering why we need PPAs when we already have the official Ubuntu repository available to us.
    5. The explanation is that not every software is immediately added to Ubuntu’s official repository, as is the case with other operating systems.
    6. Only the most reliable software is included on this list.

    Consider the following scenario: you’ve created a fantastic Linux program and want to deliver regular updates to your users, but it will take months before your application can be included in Ubuntu’s repository (and it may not be added at all).In certain instances, a PPA is really useful.In addition, the newest version of an application is not always available in Ubuntu’s official repository, which is a problem.This is done in order to maintain the stability of the Ubuntu operating system.
