unable to upgrade from 10.04 to 10.10 distro

Asked by rkcarney

I recently upgraded my machine and loaded distro 9.04 from a disk that I had used before. From this distro I have progrssively upgraded to 10.04 (LTS) distro and have spent a while loading favourites onto disk, and have had difficulty getting an MP3 ripper for some of my music to work with Sound Juicer, but I'm sure I can resolve this problem later.
Hence I decided to upgrade to 10.10 Ubuntu. When I started the upgrade at the second stage I got an error message:
An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
and advice to use either Package manager or an apt-get install command in Terminal.
Using Package Manager I searched to the best of my abilities, but could find no breaks or missing packages.
Using Terminal commands (am a complete amateur) as sudo apt-get intall gave me a package it suggested I install, which I did and then attempted to upgrade again, but keep getting the same Error Message. Now I'm stuck!

sudo apt-get update; sudo apt-get -y upgrade

Thanks

This can be a duplicate of bug 721306 and bug 658458 (and a dozen 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.
