Lorsque j'ai installé Gnome sur Unity, à la connexion, je ne pouvais pas choisir de revenir au bureau standard d'Unity. Chaque fois que je tente la simple
sudo apt-get install ubuntu-desktop
Je reçois l'erreur

J'ai tout essayé, mais Unity refuse de se réinstaller, et je ne veux pas réinstaller Ubuntu complètement. J'utilise Ubuntu 14.04. S'il vous plaît, aidez-moi ! !!
