Samba packages cause error when upgrading Saucy to Trusty

[Trifon Trifonov]

After starting an upgrade from Saucy to Trusty via the update-manager GUI, a dialog box was shown with the following information.

UPDATE: Problem was resolved after purging several Samba-related packages, apt/history.log attached.

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.

It seems like the samba-related packages were the culprit, after purging them the upgrade went fine. Attaching an excerpt from /var/log/apt/history.log, which lists the packages I had to purge in order for the upgrade to go through.

Nevertheless, I am keeping this bug report open, as these were standard packages and should have been handled gracefully by the updater. I would be glad to provide more information if someone is interested.
