[Bug 1075235] [NEW] Upgrad-manager U 11.04 to 11.10 fails

[bsalem]

Public bug reported:

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

 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

The first two items don't apply. I went into the software manager and looked at "other" packages and removed one that I
knew was unsupported. Several  other packages got removed too. Tried the upgrade again and it failed in the same way. Do I have a corrupted package list?  I guess I am going to need shell commands to diagnose this.

My /home is within the boot partition and that is how Ubuntu installs. It would be nice for there to be an option at install to
create a separate partition for /home so that in case an system cannot be upgraded, it can be reinstalled without threatening /home. I was going to do all that instead of trying upgrades and did one upgrade from 10.10 to11.04 which as soon as I got there went out of support. Versions of Ubuntu should have longer support cycles. And apparently the upgrade process is not very robust, either.
