As suggested I removed the nvidia-glx and nvidia-kernel-1.0.9629 packages, and although wasn't lucky and ended up without X (I don't know how that could have been avoided) I have managed to reconfigure things with the ubuntu packages. Software update has run a few times now without the error. Thanks for the help, and sorry for the hassle!
