Instalacija VirualBox-a na Ubuntu Desktop 12.04

Instalacija Oracle VM VirtualBox na Ubuntu Desktop radnoj stanici:

On 12.10, these solutions all failed for me. However the following worked:

1. sudo gedit /etc/apt/sources.list.d/vbox.list and paste in this line, then save:
   

   deb http://download.virtualbox.org/virtualbox/debian quantal contrib
   

2. run sudo apt-get update && sudo apt-get -y upgrade to update your machine to the latest
3. Run sudo apt-get remove virtualbox*. Then install Oracle's version: sudo apt-get install virtualbox-4.2

Should work now. Don't forget to download the extension pack from http://www.virtualbox.org as well.
