Je suis sous Ubuntu 13.04. Après avoir effectué une mise à niveau normale, Unity a disparu (après la connexion, j'ai le bureau, sans la barre de lancement, statut, sans tiret, etc.).
Si j'essaie de réinstaller ubuntu-desktop, j'obtiens des dépendances non satisfaites:
vmalep@x220t:/mnt/sda2/home/vmalep$ Sudo apt-get install
ubuntu-desktop Reading package lists... Done

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
ubuntu-desktop : Depends: unity but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
L'unité est un peu plus explicite:
vmalep@x220t:/mnt/sda2/home/vmalep$ Sudo apt-get install unity

The following information may help to resolve the situation:
The following packages have unmet dependencies.
unity : Depends: libunity-core-6.0-5 (= 7.0.0daily13.04.18~13.04-0ubuntu1) but it is not going to be installed
Depends: unity-common (= 7.0.0daily13.04.18~13.04-0ubuntu1) but 7.0.0daily13.05.16ubuntu.unity.experimental.certified-0ubuntu1 is to be installed
Recommends: gnome-control-center-unity but it is not going to be installed
Recommends: unity-lens-friends but it is not going to be installed
Recommends: unity-lens-shopping but it is not going to be installed
Recommends: indicator-bluetooth but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Essayez ces commandes:
Sudo apt-get install --reinstall ubuntu-desktop
Sudo apt-get build-dep ubuntu-desktop
Cela devrait réinstaller le bureau Ubuntu et créer les dépendances.
J'espère que cela t'aides.
La sortie indique que votre package est plus récent que celui dont dépend Unity:
unity : Depends: libunity-core-6.0-5 (= 7.0.0daily13.04.18~13.04-0ubuntu1)
C'est probablement causé par un ppa. Vérifiez le dernier ppa que vous avez ajouté, puis supprimez-le avec ppa-purge.
Pour installer l'unité, vous devez d'abord installer toutes les recommandations une à une à l'aide du gestionnaire de paquets sypnatic. Dans sypnatic, le gestionnaire de paquets recherche gnome-control-center-unit, unit-lens-friends et tous les autres. Après avoir installé toutes les recommandations, essayez d’installer l’unité, comme avant.
