Title:
  upgrade from 14.4 to 15.4 : Impossible d'évaluer la mise à niveau

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  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-release-upgrader-core' dans
  un terminal.
