Could not calculate the upgrade
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-release-upgrader-core' in a terminal. If
- you want to investigate this yourself the log files in
- '/var/log/dist-upgrade' will contain details about the upgrade.
- Specifically, look at 'main.log' and 'apt.log'.
