Remove an application
An application is software that has a graphical user interface (GUI). You can use Ubuntu Software to remove applications that you no longer use.
Applications are available in two formats: snap packages and Debian packages. An application available as a snap package is from now on referred to as a snap. In order to remove (or install) a snap you have to log on to the Snap Store/Ubuntu One. Some applications are available in both formats. In such a case in Ubuntu Software the snap will be listed first.
You may also wish to remove software that does not have a GUI. To remove such software, you can use Synaptic does not list snaps.. Note that
To remove an application:
Click the Ubuntu Software icon in the Dock, or search for Software in the Activities search bar.
When Ubuntu Software opens, click the Installed button at the top.
Find the application that you want to remove by using the search box or by looking through the list of installed applications.
Select the application and click Remove.
Confirm that you want to remove the application.
If you're removing a snap, log on to the Snap Store/Ubuntu One.
You will be asked to authenticate by entering your password (that is, your user password, not your Snap Store/Ubuntu One password). After you have done that, the application will be removed.
Some applications depend on other applications to work properly. If you try to remove an application that is needed by another application, both will be removed. You will be asked to confirm whether you want this to happen before the applications are removed.
