Public bug reported: I was trying to upgrade ubuntu 16.04 LST t 18.04 LTS. However, it fails giving the following information:

Done Building dependency tree Reading state information... Done Calculating the changes Calculating the changes 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. Restoring original system state Aborting Reading package lists... Done Building dependency tree Reading state information... Done === Command terminated with exit status 1 (Thu Aug 2 09:57:31 2018) === I removed the unofficial repositories ppa s from the repository list before the upgrade. Also, normal update runs fine in 16.04, so this is something that has to do with the repositories added by the release- upgrader tool.
