upgrade from 12.10 to 13.10 crashed

[Paul]

When installing new softwarechannels I get the error :

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

Indien niets van dit alles van toepassing is, meld deze fout dan a.u.b. met behulp van de terminalopdracht 'ubuntu-bug ubuntu-release-upgrader-core'.

And I did the ubuntu-bug and that brought me here.
