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.

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.
