[Bug 1242333] Re: upgrade to 13.10 not possible

[saber]

i have the same problem with upgrading to 13.10 release, it says that it's impossible to do the calculation for upgrade.
The message that i've in terminal is in french i don't know if that will be useful or not but this is what i've got :

"32.1 M o téléchargés en 6s (0  o/s)

Vérification du gestionnaire de paquets
Lecture des listes de paquets… Terminé
Construction de l'arbre des dépendances
Lecture des informations d'état… Terminé
Construction des structures de données… Terminé

Calcul des modifications en cours

Calcul des modifications en cours

Impossible d'évaluer la mise à niveau

An unresolvable problem occurred while calculating the upgrade.

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 tout cela ne s'applique, veuillez signaler ce bogue en
utilisant la commande 'ubuntu-bug ubuntu-release-upgrader-core' dans
un terminal.

Restauration du système dans son état d'origine

I have also attached the main.log file from /var/log/dist-upgrade

Hope read you forward.
Thanks
