I'm using Ubuntu 10.04 and kernel: 2.6.38-11-generic-pae. While using VirtualBox, i got this error:

Kernel driver not installed (rc=-1908)

Please install the virtualbox-ose-dkms package and execute 'modprobe vboxdrv' as root.

I tried to execute the command: sudo modprobe vboxdrv and got this error:

FATAL: Module vboxdrv not found.

After that, i execute this: sudo aptitude install virtualbox-ose-guest-dkms

duongnv@duongnv-laptop:~$ sudo aptitude install virtualbox-ose-guest-dkms
