Probleme mise a niveau distribution

Salut,

Oui c'est sûrement la source du problème ;-\

Par contre s'il n'a jamais fait de mises à jours, un upgrade risque de faire de gros dégâts ;-(

Je suis d'accord avec toi.
D'ailleurs je voulais juste lui montrer d'où ça vient et comment il peut éliminer le problème.
Ensuite le conseil aurait été de sauvegarder ses données avant de faire des bêtises ;-)

Même genre de problème, j'ai ce message quand je veux simplement lancer une maj. Mon install date de plusieurs années et j'ai pas mal bidouillé (et souvent dans le vide^^).
J'ai donc tapé cat /etc/apt/sources.list dans la console et j'obtiens ceci :
