Gnome ne s'installe pas sur Ubuntu 16.04
Hier, j'ai installé KDE Plasma sur mon Ubuntu 16.04.1 comme je l'ai mentionné dans cette question "Echec de la récupération" lors de l'installation de KDE et j'ai eu un problème d'écran noir. Je pouvais me connecter avec KDE et j'avais un pointeur de souris, mais je ne pouvais rien faire à part me déconnecter. Un de mes amis sur le chat askubuntu m'a suggéré d'installer un ordinateur de bureau plus léger. J'ai pris Gnome 3 mais, malheureusement, je ne sais pas pourquoi il ne s'installe pas. J'ai lancé Sudo apt-get install ubuntu-gnome-desktop et j'ai obtenu le résultat suivant:

You might want to run 'apt-get -f install' to correct these:

Le problème est que KDE n'est que partiellement installé, il est donc en conflit avec GNOME et le gestionnaire de paquets. Commencez par supprimer KDE. Ensuite installez GNOME 3. Veuillez commenter si vous avez besoin d’aide supplémentaire.
