I’ve ran twice into this problem. After doing an update on Ubuntu, Virtual Box gave me the message below :
It seems that this happens when we update some headers. My problem was that running /sbin/vboxconfig did not solve the issue. Thanks to a post on the Untuntu Forum, here is how to fix it :
sudo apt-get install linux-headers-generic build-essential dkms sudo apt-get remove --purge virtualbox-dkmssudo apt-get install virtualbox-dkms
Restart the system and the problem should be fixed.
