After reading my guide on how to install Ubuntu , you were positively impressed with this free operating system and are doing everything to understand how it works. But now you are faced with a small obstacle: you want to uninstall an application that you previously installed on your computer but you don’t know how.
Do not fear! It is a simple operation at least as much as the one that is performed to uninstall a program from Windows, even more if we evaluate the tedious uninstallation procedures of some programs (those in which you have to click countless times on “Next” or on “Next” ). So do not waste any more time and find out now how to uninstall a program on Ubuntu thanks to the instructions below. I assure you that you will not find the slightest problem in achieving your goal.
Just a little clarification before starting: for the tutorial I used Ubuntu 18.04 which, at the time of writing, is one of the most recent versions of this famous distro. That said, the directions in the article should be valid for all the latest versions of Ubuntu, so you shouldn’t find any particular problems in putting them into practice. Happy reading and good “cleaning” of your computer from unwanted software!
Uninstall a program from Ubuntu Software
If you want to learn how to uninstall a program on Ubuntu , the easiest way you can go is to use Ubuntu Software , the store integrated in all the latest versions of Ubuntu, through which you can not only find and install new applications on your PC, but also to remove the previously installed ones in an extremely simple way: let’s see how it works together.
The first step you need to take is to start Ubuntu Software by clicking on its icon in the sidebar of the desktop (the orange shopping bag with the letter “A” printed in the center). In the window that opens, then select the Installed tab , search for the application to be removed and proceed with its uninstallation by clicking first on the Remove button located in front of its name and then on the same button contained in the window that appears on the screen.
Alternatively, if you do not want to waste time scrolling through the list of all the software installed on your computer, select the All tab of Ubuntu Software, click on the magnifying glass icon located at the top right and look for the name of the program that you want to uninstall in the search field that appears on the screen.
To conclude, click on the name of the software to be removed from the computer (which in the meantime should have appeared in the search results), press the Remove button on the page that opens and confirm, pressing again on Remove .
To complete the operation, in both cases, you will be asked to enter the password of your user account (the one you use to access the system). Enter it, then, in the text field that appears in the center of the screen and confirm by pressing the Authenticate button (or the Enter key on the keyboard).
Uninstall a program from Ubuntu via Synaptic Package Manager
Can’t find the program you want to uninstall inside Ubuntu Software? Obviously this is a software that you have installed “manually” via the .deb package: in cases like this, it happens that the software does not appear in Ubuntu Software. In any case, don’t worry: there is a solution to this too.
The solution to your problem is called Synaptic Package Manager and, as its name suggests quite easily, it is a software that allows you to manage all the packages installed on your computer, including system components and third-party applications, in a very simple way . Using it, you can select the packages related to the programs you want to uninstall and remove them all in one go.
To use Synaptic Package Manager, you must first install the latter through Ubuntu Software. So start Ubuntu Software , click on the magnifying glass icon located at the top right and look for Synaptic Package Manager . Once the search results have appeared, click on the name of the Synaptic Package Manager , in order to view the software description sheet, then press the Install button , type the password of your user account on Ubuntu and wait for the download and automatic installation of the program.
Well: now you just have to start Synaptic Package Manager (by clicking on the Start button of Ubuntu Software or looking for it in the main menu of the system, the one that appears by clicking on the icon with the 9 white dots located at the bottom of the sidebar of the desktop) and re-type your user account password on Ubuntu.
Once this is done, select the Status item and then the Installed one from the left side menu and find the packages related to the programs you want to uninstall from the PC. If you can’t find the right packages, search for them using the Search function available in the top menu (the packages installed on your PC are the ones that have the Ubuntu icon next to the name).
To conclude, right-click on the names of the packages to be uninstalled, select the item Remove completely from the context menu and, when prompted, answer Select the warning that appears on the screen to also select the connected packages. If you do not want to remove all packages and data related to a specific application (because, perhaps, you think you can reinstall it in the future), select the Remove item instead of the “Remove completely” item from the contextual menu of Synaptic Package Manager.
Once you have selected all the packages to be removed, click on the Apply button located at the top left, answer Apply to the warning that appears on the screen and, if necessary, re-enter the password of your account on Ubuntu.
Note: use Synaptic Package Manager with great caution as, as already mentioned, this software also allows you to act on system components. Make sure to select only the packages related to the programs you want to remove from your PC (maybe do a Google search to make sure you have not selected system components).
Uninstall a program from Ubuntu via Terminal
Another way to uninstall a program on Ubuntu is to remove application packages via Terminal . It is, however, a fairly complex procedure when compared to those seen previously, so consider it only if you know well where to get your hands or, in any case, if you need to deepen the operation of this important tool included in Linux systems ( and not only).
To uninstall a software from Terminal , open it by looking for it in the system menu (the one that appears by clicking on the button with the 9 white dots in the sidebar of the desktop). With Terminal started, you need to find the name of the package to be removed: to do this, type the command dpkg-query -l , give Enter and check what is the name of the package associated with the program you want to remove from the system.
Alternatively, if you want to find only packages related to a specific application, you can use the dpkg-query -l ‘thunderbird *’ command , where instead of thunderbird you have to type the name of the program you want to remove from your computer.
At this point, you just have to give the command sudo apt-get purge [package name] , type the password of your user account and answer S to the request to remove the package to complete the operation.
If you want to delete an application while keeping its configuration files on the PC (useful move in case you want to reinstall the program), use the command sudo apt-get remove [package name] .
Note: also for uninstalling programs from Terminal, the same recommendation that I made to you before, speaking of Synaptic Package Manager, applies. Since it is possible to delete the system software packages, before proceeding with the cancellation of any package, do a search on Google and make sure you are not going to make some “mess”). Then don’t tell me I didn’t warn you!
