Bug Description
Running Lubuntu 14.04, I tried to upgrade to 14.10 with:
$ update-manager -d &
I pressed the ‘Upgrade’ button, then got a window with the release information, which started:
Welcome to the Ubuntu 'Utopic Unicorn' development release
This release is still in development. Do not install it on production machines.
That isn't right (it has now been released), but I proceeded anyway.
Could not determine 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-
None of the above apply, hence this report.
