[Bug 884152] Re: Error: Marking the upgrade (from 11.04 to 11.10) - unresolved package dependencies

Looks like its the xorg PPA causing the problem.  It was made for the maverick release.  You will need to remove that PPA and its packages that were installed with it.  Consider using the command line tool 'ppa-purge'.
