Issues with VirtualBox on Ubuntu 12.10

Problem:

Are you having issues starting virtual box after installing updates?  Annoying isn't it?  Errors like the following:

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.

Maybe you have an issue with the networking card when operating in bridged mode and get an error similar to the following (note might also say HostInterfaceNetworking-wlan0) :

Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_PERMISSION_DENIED). Failed to attach the network LUN (VERR_PERMISSION_DENIED)

Solution:

VirtualBox recommends you run sudo /etc/init.d/vboxdrv setup but unfortunately this is not available on most Ubuntu installations.  I would recommend running the following:

sudo apt-get install linux-headers-$(uname -r)
sudo apt-get --reinstall install virtualbox virtualbox-dkms 
sudo modprobe vboxdrv
sudo modprobe vboxnetflt
sudo modprobe vboxnetadp

Good luck!
