[Bug 1309520] [NEW] unable update 13.10 to 14.40

[Joris Hoeksema]

Public bug reported:

I keep being unable to update my Ubuntu 13.10 to 14.10.
At first it was giving me errors about packages that "had no cache" (an example of this was a package named "zsnes", which I removed, afterwards the error didn't show up again), but now it hangs on "Calculating changes..." in the Distribution Update screen with the message:

"Could not calculate the upgrade

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

If none of this applies, then please report this bug using the command
'ubuntu-bug ubuntu-release-upgrader-core' in a terminal."

In advance to upgrading I had already disabled my xorg-edges PPA since that would cause trouble according to some.
Also note: Between "Preparing for upgrade..." and "Setting new software channels..." it gives me a notice saying: 

"Third party sources disabled

Some third party entries in your sources.list were disabled. You can re-
enable them after the upgrade with the 'software-properties' tool or
your package manager."

I'm unsure whether this is relevant or not but it might have something
to do with it.
