I installed Libre Office 6.2, then it would not launch (the icon appeared in the dock, then disappeared a few seconds later). I then reinstalled Libre Office 6.1 and that works fine, but I can't see how to remove 6.2. The sudo apt remove libreoffice 6.2 does not work, there is no right-click to uninstall in the app list. Any idea? Thanks! Fred
Fred, welcome back!
I did not install LibreOffice via Flatpak, however, I do have some experience with Flatpak.
Here is the online manual regarding the Flatpak command.
The TLDR CliffsNotes version boils down to this.
1. Go to Applications -> Terminal (Win+T)
flatpak list --app --show-details
3. You should see a LibreOffice line with the following information: 6.2 stable x86_64 flathub system org.libreoffice.LibreOffice...
4. It is that last part that we care about. The uninstall command would be:
flatpak uninstall org.libreoffice.LibreOffice
6. After the uninstall is successful, press Cont+D to exit the Terminal.
Also try executing
sudo snap remove libreoffice if the above process don't work.
I hope that helps! Good luck.
