I made a backup of my system using Timeshift, and updated to Kubuntu 20.10, and I had multiple issues, so I decided to use my backup to rollback to Kubuntu 20.04, but Snap applications stopped working.
I tried to run Glate in the terminal, and I got this error:
cannot locate base snap core18: No such file or directory
And with Citra Nightly I got this error:
cannot locate base snap core20: No such file or directory
I tried reinstalling
snapd, but that did not work.
I tried to install
core20, but they are already installed.
I tried to remove core18, but I got this error:
error: cannot remove "core18": snap "core18" is not removable: snap is being used by snaps glate, gnome-3-28-1804, gnome-3-32-1804, gtk-common-themes, qt513 and 2 more.
Removing core20 is not possible either
error: cannot remove "core20": snap "core20" is not removable: snap is being used by snap citra-emu.
I tried removing Glate, and installing it again, but that does not work.
I can not purge snapd, and installing it again, because that will remove all my Snap application, and their settings, and that includes all the save games of Citra, and I do not know where this application stores its save games exactly to backup them.
