Impossible d'évaluer la mise à niveau

An unresolvable problem occurred while calculating the upgrade:
E:Erreur, pkgProblemResolver::Resolve a généré des ruptures, ce qui a pu être causé par les paquets devant être gardés en l'état.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

Si rien de ceci ne convient, veuillez signaler ce bogue concernant le paquet « update-manager » en y joignant les fichiers du dossier /var/log/dist-upgrade/.
