Virtual Box Error

So i have been trying to get vmare to work and now virtualbox. Both came up with an error relating kernel driver/headers. So currently the error is:

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/etc/init.d/vboxdrv setup'

as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

To begin with i tried finding "vboxdrv setup" however i didn't find it. Following i search up the error and the suggestions where to try run the following command (/Source):

sudo apt-get install linux-headers-3.5.0-17-generic

But when i run that command i get the following error:

Couldn't find any package whose name or description matched "linux-headers-3.5.0-17-generic"

Couldn't find any package whose name or description matched "linux-headers-3.5.0-17-generic"

No packages will be installed, upgraded, or removed.

0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Need to get 0 B of archives. After unpacking 0 B will be used.

So my question is where can i get the "linux-headers-3.5.0-17-generic", and where should i place them so they run properly?
