In the newly installed Ubuntu 9.10 Karmic our system one of the most useful is undoubtedly VirtualBox. VirtualBox allows you to create virtual machines on your computer. Programs that run within those virtual machines really believe they are running on a real physical computer. Here in Ubuntux.info other times we talked about Virtualbox

VirtualBox is in the repositories, but with an older version than the official, limited by licensing issues. To have the latest version of VirtualBox on Ubuntu 9.10 Karmic Koala us we should only run in a terminal the following commands:

The first is to add the official repositories of VirtualBox with:

sudo wget http://ubuntux.info/apt/virtualbox.9.10 -O /etc/apt/sources.list.d/virtualbox.9.10.list

Recovered the PGP key:

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

And finally update the repositories and install VirtualBox 3.0 ordered

sudo apt-get update && sudo apt-get install virtualbox-3.0

This is ready Virtualbox installed on our system. A new option will appear under Applications -> System Tools -> Sun Virtualbox.
