Still no luck with this. I have removed the nouveau and so on and ran update-manager -d - as various people have suggested.
I am beginning to think that the only way to upgrade is to do a vanilla reinstallation. This will be particularly inconvenient, being as I have VBox with Win7 installed, and that means I will probably have to call Microsoft to get the licence working again as each Windows doesn't like having its virtual container updated. All in all, it is going to be a real big time-consuming hassle, if I have to do a vanilla installation, so some clear instruction would be very gratefully received.
