Bug Description

The only error I get is:

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

The upgrader does gracefully fail back to my current installation, but I am unable to complete the upgrade.

One more clue: In /var/log/dist-upgrade/main.log, I see the message:
