Public bug reported: After making sure my system is up-to-date, I ran the upgrade tool and got the following when "Setting new software channels":
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. I got some details of my system in case they were useful.
