Voici le résultat que j'obtiens lorsque j'essaie d'exécuter sudo apt-get update ou lorsque j'essaie d'installer quoi que ce soit.

W: Some index files failed to download. They have been ignored, or old ones used instead.Je ne peux pas non plus accéder à github, ce qui m'indique que l'accès à github n'a pas pu être résolu.
Une idée de ce qui pourrait causer cela ?
