Impossible d'évaluer la mise à niveau
Un problème insoluble est survenu lors de la préparation de la mise à niveau.
Ceci peut-être dû à :
* la mise à niveau vers une version de développement d'Ubuntu ;
* la version de développement d'Ubuntu est actuellement utilisée ;
* des paquets logiciels non officiels, non fournis par Ubuntu.
Si rien de tout cela ne s'applique, veuillez signaler ce bogue en utilisant la commande « ubuntu-bug ubuntu-

Reviewing the files from your upgrade attempt you seem to have enabled a PPA that provides Xorg packages. This will prevent the upgrade as that PPA contains package version numbers greater than the release to which you are upgrading. You can revert the PPA by installing the ppa-purge package from the official Ubuntu archive and then running 'sudo ppa-purge oibaf'. After that you try upgrading and again and if it still fails open a new bug report. Thanks and good luck!
