Uninstalling applications ​

These instructions will show you how to uninstall any application installed through Flatpak.

To just uninstall an application and keep its data in   ~/.var/app/<app-id>  intact, you can run: 

      flatpak uninstall <appid>
You can also use   flatpak remove <appid>   as   remove   is an alias for   uninstall . anger

This will uninstall all application data stored by Flatpak. Please proceed carefully.

To uninstall and also delete the data from   ~/.var/app/<app-id>, you can run: 

      flatpak uninstall --delete-data <appid>

It will ask you to confirm using   y/N  before proceeding. Anything stored outside of   ~/.var/app/<app-id>  is outside of Flatpak's control and might be left as is.

Often you may have multiple branches of an application installed, for example   beta  and   stable  or the same application installed from multiple different remotes or the same application installed both in system and user locations.

Then   flatpak uninstall  will present you with a choice for the specific ref and location to uninstall. For example: 

      $ flatpak uninstall org.example.foo

Similar installed refs found for ‘org.example.foo’:

   1) app/org.example.foo/x86_64/stable (system)
   2) app/org.example.foo/x86_64/beta (system)
   3) app/org.example.foo/x86_64/beta (user)
   4) All of the above

Which do you want to use (0 to abort)? [0-4]:

If you want only the   beta  branch uninstalled from the   system  location, choose type   2  in the terminal.

note

Please be careful not to pass   --delete-data  here, if you want to keep some of them installed.

If you want all of them uninstalled, type   4  in the terminal.

You can also uninstall applications from software stores provided by your desktop environment or distribution like GNOME Software or KDE Discover.

Uninstalling unused dependencies ​

Often when you have uninstalled a bunch of applications, there might be leftover runtimes that aren't needed anymore. To remove them you can run:

      flatpak uninstall --unused

Removing remotes ​

If you want to delete the remote too, you can run:

      flatpak remote-delete <remote-name>

To see a list of remote names, you can run:

      flatpak remote-list

If you have applications or runtimes still installed from that remote, you will be asked whether to remove them too.

If you want to just remove the remote but keep applications installed you can run:

      flatpak remote-delete --force <remote-name>
