Re : pas de connexion wifi
Salut
La commande cat n'a rien retourné, elle n'est pas présente sur ton installation 
Essaie en faisant : nano /etc/network/interfaces et copie-colle le contenu. Ne passe pas par sudo, tu éviteras de modifier le fichier par erreur 
N'oubliez pas de consulter la documentation pour vous donner un coup de main !
Merci de modifier le premier message de votre sujet pour ajouter [Résolu] lorsque votre problème l'est :)
Xubuntu 20.04 sur deux ordinateurs, zéro souci. Passez à Xubuntu ;)
