Ajoutez exit 0 après Shebang à /var/lib/dpkg/info/snapd.prerm.

Ensuite, supprimez un paquet dpkg --purge --force-all snapd.

Vérifiez vos sources pour la fiabilité rgrep 'xenial' /etc/apt et supprimez toutes les sources correspondant à la version incorrecte de snapd.

Exécutez apt-get update et mettez à niveau un système pour qu'il soit dans un état cohérent.
