Public bug reported: Here is the text (in french): Impossible d'évaluer la mise à niveau
Un problème insoluble est survenu lors du calcul de la mise à niveau. Si rien de tout cela ne s'applique, signalez ce bogue à l'aide de la commande « ubuntu-bug ubuntu-release-upgrader-core » dans un terminal. Si vous souhaitez analyser le problème par vous-même, les fichiers journaux contenus dans le répertoire « /var/log/dist-upgrade » contiennent les informations sur la mise à niveau. Plus précisément, veuillez consulter les journaux « main.log » et « apt.log ». I can transmit main.log and apt.log if you wish. Thanks.
