Ubuntu 11.10 failing to upgrade

[the_blue_box]

Hi everyone, I've got a bit of a of a problem with my install of Ubuntu 11.10 (that I haven't used in a while) in that is whenever I try to upgrade it to 12.04 I will get to...

setting new software channels

then gives


Could not determine the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Unable to correct problems, you have held broken 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

If none of this applies, then please report this bug using the command 'ubuntu-bug update-manager' in a terminal.

I think it has something to do with the linux-image not being up to date but I'm not sure

Any help would be much appreciated!

Thanks
