Comment réparer le cache de paquet corrompu dans Ubuntu
Chaque fois que j'essaie d'installer un nouveau paquet dans Ubuntu 16.04, le message d'erreur suivant s'affiche:
Le fichier de cache du paquet est corrompu
J'ai essayé les commandes Sudo apt-get update et Sudo apt-get upgrade mais elles ont également échoué. Ça montre:

Comment puis-je réparer ça?
Le premier problème est ce référentiel: https://launchpad.net/~chris-lea/+archive/ubuntu/node.js/ . Comme vous le voyez, il n’existe pas de paquet xenial. Pour résoudre ce problème, ouvrez Software & Updates dans l’onglet Other Software et supprimez ce ppa ou cliquez sur Editet remplacez xenialpar utopicsi vous avez besoin du package contenu dans ce référentiel.
Le deuxième problème est le ppa de virtualbox. Retirez le ppa comme avant et suivez les instructions ici: https://www.virtualbox.org/wiki/Linux_Downloads (vous avez peut-être oublié d'ajouter la signature de clé).
