le "See" qui me semble poser problème est juste après la ligne = = = = (il n'a pas de # avant)
et après la ligne ------ figurent les lignes que j'ai écrites ce matin.
J'observe qu'elles figuraient déjà dans le fichier, mais avec les différences suivantes :
- pas de "fr." au début de chaque adresse
- pas de / derrière le dernier ubuntu (dans chaque adresse)
- pas de ligne en "deb
http://security.ubuntu.com etc" mais toujours "archive" à la place de "security".
Que faut-il que je modifie ?
