This can be a duplicate of bug 721306 and bug 614993 (and dozens of similar ones)

If the package xserver-xorg-video-nouveau is installed, in several cases the 10.04 to 10.10 upgrade fails with the error message

"Could not determine 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"

Several persons have reported that after removal of that package the upgrade was successful.

Try this workaround: Open a terminal and enter the command:

sudo apt-get remove xserver-xorg-video-nouveau

and try the upgrade again.

OR:
If you indeed have a held or broken package please follow the instructions in

 i tried what you suggested in your reply and this is what its telling me. does this mean theres a broken package?

The following packages have unmet dependencies:
  libdrm-nouveau1: Breaks: xserver-xorg-video-nouveau (< 1:0.0.16) but 1:0.0.15+git20100219+9b4118d-0ubuntu5 is to be installed

im pretty sure its not a duplicate. i tried the stuff on 721306 but it still wont let me update or upgrade

@Jesse:
...
$ apt-get remove xserver-xorg-video-nouveau
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

You missed to put "sudo" in front of the command

sudo apt-get remove xserver-xorg-video-nouveau

Even if your case maybe is not fully identical to bug 721306, removing xserver-xorg-video-nouveau should help solving your 'held package' problem.
