Bug Description
I'm using 12.04 LTS, and the update manager tried to upgrade to 14.04.1 LTS.
In the section for new software channels, it was at the part where it was calculating changes, but it stopped saying that an unresolvable problem occured. Below is the message. After I pressed okay on the window, the upgrader restored the original settings before quitting.
"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-
