Upgrade to 11.10 beta (from 11.04) fails

[Dan Wood]

From terminal, I ran "update-manager -d"

Failed with "Could not get exclusive lock" - I couldn't see any reason why, so repeated the attempt.

On 2nd attempt, dialog box appears:
"After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore. This indicates a serious error, please report this bug using the command 'ubuntu-bug update-manager' in a terminal and include the files in /var/log/dist-upgrade/ in the bug report".

So, that's what I'm doing now :)
