Partenaires Canonical manquants et référentiels indépendants dans Ubuntu 14.04
J'ai rencontré un problème étrange aujourd'hui lorsque j'ai constaté que des partenaires Canon et des référentiels indépendants avaient disparu de l'onglet "autre logiciel" de l'onglet "logiciels et mises à jour". J'ai également remarqué que "principal", "univers", "multivers" et "restreint" sont tous désactivés, ainsi que "trusy-security", "trusty-updates", "proposé par trusy" et "trusty-backports".
La question qui se pose est la suivante: comment puis-je rajouter des référentiels Canonical et indépendants afin de pouvoir les réactiver? et qu'est-ce qui a pu causer ça?
Merci d'avance.
