I recently installed Ubuntu 10.04 Lucid onto my Macbook Pro 8.1 over my Mac OS, and I am having many issues. The wireless is not working, the software update window will respond just long enough to get my hopes up, right click will not work, the mac hotkeys refuse to work, and the ubuntu software center spouts that all of the provided packages are "unverified", and outright refuses to let me install anything, even a software bit that worked on my last macbook/ubuntu install. HELP!?!?!?!
