Bonjour,
Comme beaucoup, j'ai un problème de wifi depuis l'installation de la version 16.04 d'ubuntu.
Je dois également dire que lors de l'installation, mon ordinateur a planté et j'ai du installer certains paquets a la main. Il semble cependant que j'ai mal fait ce travail puisque le fichier sso-ubuntu-client est incomplet sur mon ordinateur (je ne peux plus ouvrir ma logithèque).
Je vous mets toutes les informations necessaires (enfin j'espère :p )
