I'd recommend a slightly differently approach. First of, remove snap all-together. Continue removing snap packages until there are none left. sudo snap remove firefox sudo snap remove gnome-3-38-2004 sudo snap remove gtk-common-themes sudo snap remove core20 sudo snap remove bare sudo snap remove snapd Remove snap completely: sudo apt purge snapd Then instead of adding the ppa, use flatpak with flathub (https://flatpak.org/setup/Ubuntu https://flatpak.org/setup/Ubuntu)
