package virtualbox-ose 4.0.4-dfsg-1ubuntu4 failed to uninstall: the pre-removal script returner error status 1

[Antonios Anastasiadis]

It seems that the module vboxnetadp cannot be unloaded, as it is probably in use.
The uninstallation stops at:

 * Stopping VirtualBox kernel modules
* Cannot unload module vboxnetadp [fail]

If you want to uninstall virtualbox-ose try this:

- entry in the system using recovery option
- use netroot option (console with user root and networking).
- use dpkg -P virtualbox-ose, to purge the packages

This works for me, I think that if you entry in this way in the system, vboxnetadp module is not loaded and you can perform the uninstall
