I have looked through this forum but I can't see the exact information I would like. I installed the latest virtualbox from the web to Synaptic package manager and then downloaded it. I have Ubuntu 8.04. When I came to use it I got the Virtualbox kernel driver not installed, I know this is a regular problem but I have done this and that trying to fix it I now think the best I can do now is start again and un-install but I have read nothing on how this is done in my particular situation. So please how do I un-install. I have seen on these forums how to really install Virtualbox so I will try again.
Did you try this tutorial? http://www.howtoforge.com/installing-virtualbox-2.0.0-on-ubuntu-8.04-desktop
