Bonjour abelhorne,
Merci de ton aide aussi.
abelthorne a écritSurtout pas de do-release-upgrade en l'état.
Donc, commence par éditer le sources.list :
sudo nano /etc/apt/sources.list
Supprime la dernière ligne, enregistre (ctrl + O, valide le nom de fichier avec entrée, ctrl + X pour fermer Nano), puis recharge la liste des dépôts :
sudo apt-get update
et redonne à nouveau le retour de la commande suivante :
apt list | grep "installé, local"
Voici le contenu du fichier /etc/aptt/sources.list après modification :
