[Bug 1242284] [NEW] The upgrade to 13.10 could not be calculated, though I'm running the official 13.04 version

[Gijs ter Beek]

Public bug reported:

While upgrading my computer from 13.04 to 13.10, I got the message 'An
unresolvable problem occurred while calculating the upgrade'. I only use
the official Ubuntu-repositories and some ppa's that can be switched off
without problems.
