Remove and purge the current version, then install the updates:
sudo apt-get --purge remove fglrx*
sudo apt-get install fglrx-updates fglrx-amdcccle-updates
- Reboot
Making sure fglrx is fully removed is an important step. It didn't work for me the first time I tried to install the updates and in the end I removed each fglrx package individually, purged each one individually, removed no longer dependencies sudo apt-get autoremove, rebooted, then installed the updates sudo apt-get install fglrx-updates fglrx-amdcccle-updates, rebooted, and (as of writing) I got catalyst version 11.11 (which still doesn't work with gnome3).

12.10 Troubleshooting
If you have problems with graphics after installing or updating to 12.10, you will need to remove fglrx and use open source drivers:
$ sudo apt-get remove fglrx*
If you get stuck on a warning about "low graphics":
- Open the terminal Ctrl+Alt+F1
- Remove fglrx:
sudo apt-get remove fglrx*
- Reboot:
sudo reboot
