je vous joint le copié collé de ce que j'obtiens sur mon terminal
@penguin:~$ sudo apt-get install gimp

Merci! Ceci a parfaitement fonctionné !
Au passage faut il régulièrement faire des mise à jour des logiciels et ou du système Linux?
Et si oui quelle ligne de commande utiliser ?
Et pour nettoyer le système (hé oui, la place est comptée sur chromebook):
vide le cache de téléchargement de apt
efface tous les paquets devenus inutiles.
Ceci étant dit, les mises à jour sont assez rares, je pense qu'il devrait y en avoir une dans peu de temps car Debian est maintenant officiellement passée en version 11 (Bullseye) alors que celle qui est installée est la version 10 (Buster).
Tu envoies cette suite de commandes un fois tous les 2 ou 3 mois, ça suffit. De tout façon, linux est lancé dans une machine virtuelle donc aucune possibilité de corruption de Chrome os par un logiciel linux.
Une info : si tu veux imprimer depuis un logiciel linux (sur une imprimante en réseau), il faut installer cups (logiciel qui gère l'impression sous linux).
car beaucoup essaient en vain et ne comprennent pas pourquoi ça marche pas.
