Public bug reported:
Hi,
Trying to upgrade from Ubuntu 13.10 Saucy to 14.04 Trusty in the GUI, I
get the attached image.
Using "do-release upgrade" in a terminal, it ends in :
<<<

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.
