I remove snap then do the following to make sure it doesn't come back: cat << EOF > /etc/apt/preferences.d/nosnap.pref Package: snapd Pin: release a=* Pin-Priority: -10 EOF One thing I don't do is use Flatpack, AppImage or any substitute for snap. If I wanted that functionality, I'd use snap. I don't like apps installed via snaps (etc.) changing themselves almost seemingly stealthily.
