Virtual Box error message kernel

I don't have very good luck when installing vBox form the software center, Im sure others do, but I just don't. So i would recommend removing your current install and then installin from the site.

Code:

sudo apt-get remove --purge virtualbox

Then do a search in nautilus in your FileSystem for virtualbox and remove any leftovers.

Code:

gksudo nautilus

Then install dkms and build-essential

Code:

sudo apt-get install dkms build-essential

Then download per site instructions.

Last step, install Extension Pack

uninstal virtual box

To remove VirtualBox, I actually recommend running this command and not replacing * with anything (just run it exactly like so):

sudo apt-get remove virtualbox-\*

If you want to remove global configuration files too (this does not remove your virtual machines), run exactly this instead:

sudo apt-get purge virtualbox-\*

That method is OK, but this way may be more thorough.
