Virtualbox 3.1 in Karmic

Ubuntu Karmic uses the OSE (open source edition) of Virtualbox, which I didn't particularly like because of the limitations - no USB support, for one.

Resource site: http://www.virtualbox.org/wiki/Linux_Downloads

I downloaded the full package from the Virtualbox site here.

Then added to the end of my sources.list file the deb reference:

sudo gedit /etc/apt/sources.list

at the end of the file -

deb http://download.virtualbox.org/virtualbox/debian karmic non-free

and ran this in the terminal:

wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -

checked if I needed dkms package (to ensure that the VBox kernel gets updated when the Linux kernel is)

sudo apt-get install dkms

and finally the VirtualBox package itself:

sudo apt-get install virtualbox-3.1
