I have installed VirtualBox through the software centre, but when I try to start a VM, I get the following error:

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.

I already updated my dkms and installed linux-headers, but this /etc/init.d/vboxdrv doesn't exist.

I have been googling but I can't find an answer.
