Upgrade to VirtualBox 1.4.0

VirtualBox 1.4.0 was released yesterday, so I thought I would write a very quick guide to installing it in Ubuntu Feisty. My previous post detailed downloading the file directly and several troubleshooting steps. If you run into a problem, check that post out. Add VirtualBox Repository Open up /etc/apt/sources.list (with sudo gedit) and add this line:

deb http://www.virtualbox.org/debian feisty non-free

Add the VirtualBox Public Key

wget http://www.virtualbox.org/debian/innotek.asc
sudo apt-key add innotek.asc

Update Apt and Install

sudo apt-get update
sudo apt-get install virtualbox

If you already installed VirtualBox, you may just need a simple

sudo apt-get upgrade

after adding the repo and updating apt. Troubleshooting If you run into a error when starting VirtualBox, execute a quick:

sudo /etc/init.d/vboxdrv setup

and everything should be fine. Again, look at the previous post if you have a problem.
