I own an original disc of UT2004. It came with a linux install script ("linux-installer.sh") on the disc (If memory serves me, I think I had to copy the installer script to my home directory and run it from there.). When run, it will ask for your key code. Run the installer as root and it will install UT2004. I downloaded the newest updates (non-OS specific) from "UT2004.com". Unzip and manually copy the update files to the newly installed ut2004. Be sure to check the read.me files before you move 'em... because you need to overwrite files in the appropriate order. Happy Fragg'in..
