With Ubuntu 8.10 you only need one command to have Virtualbox running:
sudo apt-get install virtualbox-ose
You’ll find its icon under Applications – Accessories.
In Ubuntu 8.04 and prior versions:
sudo apt-get install virtualbox-ose
sudo apt-get install virtualbox-ose-modules-`uname -r`
sudo adduser $USER vboxusers
log out and log in (hit Ctrl-Alt-Backspace)
You probably need to run second command again upon any kernel upgrade.
