Public bug reported:
I just tried to upgrade the OS from Lubuntu 26.04 to 26-10, but it wasn't
possible to do so because the upgrader recognized all the packages to be set as
from an unknown source, even if everything is installed from the official
repos, so it wasn't possible to perform an upgrade
