Public bug reported: While trying to upgrade to Ubuntu 13.10 (saucy) from 13.04 (raring) via 'do-release-upgrade', I received the following error:
""" 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.
