[Bug 1393185] [NEW] Failed to upgrade from 14.04 to 14.10 using the do-release-upgrade tool

[Simon Joecks]

Public bug reported:

Switched upgrade mechanics to every version from LTS, and ran the do-
release-upgrade tool, which terminated with an error:

Checking package manager

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.
