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 don't think there's anything whatsoever unusual with this install.
It's fairly basic with mythtv .027, and ntopng.
