Following previous posts about installing Virtualbox, here’s the 2.1 update (currently 2.1.2).

If you have 2.0 already installed you need to manually install the new version.


  • Go to System > Administration > Software Sources and Third-Party Software.
  • Add the following sources for Intrepid (check your distribution here)
  • Download and register Sun authentication key
wget -q -O- | sudo apt-key add -
  • Be sure your source list is updated
sudo apt-get update
  • Be sure you have dkms installed (so Virtualbox host kernel is automatically updated as you update your system kernel)
sudo apt-get install dkms
  • Install Virtualbox 2.1
sudo apt-get install virtualbox-2.1
  • Logoff and login again
  • Start Virtualbox at Applications > System Tools > Sun xVM VirtualBox
  • If you have a Windows Virtual Machine don’t forget to install the Guest Additions (after starting the virtual machine go to Devices > Install Guest Additions).
