I am trying to go from 11.04 to 11.10 (with the final intent of bringing my system up to 12.04), using sudo do-release-upgrade (or via the gui update manager) but continually receive this error message:

Could not calculate the upgrade 

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

I know that this type of "Could not calculate the upgrade" error has been reported before, but I have tried all solutions I could find in the old bug reports and on the forums, but to no avail. I am following proper upgrade protocol (I've updated all packages, looked for broken dependencies, and cleaned up my file system). No errors are returned from sudo apt-get upgrade or sudo apt-get dist-update.

I tried the solution mentioned here (http://ubuntuforums.org/showthread.php?t=1859338), but that doesn't work. Removing libglib2-ruby1.8 as mentioned here (http://askubuntu.com/questions/109210/could-not-calculate-the-upgrade-on-upgrade-from-11-04-to-11-10) does not work either. I purged my PPA's (I only had one: ubuntugis) using PPA-purge, but that doesn't seem to help either. Running

Any help/ideas will be greatly appreciated!

All logs can be seen at the bug report I filed here: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1048400

Actually, I find that I can't paste in contents of var.log here (too long), and I can't attach a file. I'll edit my orginal post and add it there. – Isaac Ullah Sep 10 '12 at 22:25
use paste.ubuntu.com to post logs - you can add the link in your question. – fossfreedom♦ Sep 10 '12 at 22:31
Actually, the contents of the log files is too long to add to the post. Is there someway I can attach them? I suppose I could sync them them through my Ubuntu One account and grab a URL from there if necessary. – Isaac Ullah Sep 10 '12 at 22:32
Thanks fossfreedom, but it occurred to me that I had uploaded them with the bug report I filed here:bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1048400 so the logs can be seen if one goes to that URL. – Isaac Ullah Sep 10 '12 at 22:33
You can try sudo update-manager -d – Sinan Talebi Sep 10 '12 at 22:47
