Public bug reported: 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. This is the message I get when trying to upgrade from 14.04 to 14.10. I have removed all 3rd party updates but there is no change.
