Bug Description
I get the following message when trying the upgrade. It doesn't seem to be transient, I've tried several times.
An unresolvable problem occurred while calculating the upgrade.
This was caused by:
* Upgrading to a pre-release version of Ubuntu
This is most likely a transient problem,
please try again later.
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-
you want to investigate this yourself the log files in
'/var/log/
Specifically, look at 'main.log' and 'apt.log'.
