Need some help updating the OS and Uninstalling an app

Then let’s check if Flatpak knows about it.

flatpak list

Although it is about Windows, and probably not through Flatpak, i spotted an issue about the application not uninstalling properly.

flatpak install flathub lbry
flatpak uninstall lbry

If the application is still in the system, we should be able to find it.

find / -regex .*lbry.*
