This question already has an answer here:
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
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.
This is a familiar message to everyone that uses Virtual Box. This "bug" has been popping up every few months at least since 11.10. I got it today for the first time on 14.04 and unfortunately the classical solution of re-installing
virtualbox-dkms is not having any effect:
sudo apt-get install linux-headers-generic build-essential dkms sudo apt-get remove virtualbox-dkms sudo apt-get install virtualbox-dkms
What could be the reason for this old fix to fail?
Update: In the comments user bain makes reference to an old thread that apparently reports to the same problem. While the error message is similar, on Ubuntu 14.04 this issue seems to have a different nature, unrelated to the
virtualbox-dkms package. For instance, on Ubuntu 14.04 the
virtualbox package is up to date:
$ sudo apt-cache policy virtualbox virtualbox: Installed: 4.3.10-dfsg-1 Candidate: 4.3.10-dfsg-1 Version table: *** 4.3.10-dfsg-1 0 500 http://de.archive.ubuntu.com/ubuntu/ trusty/multiverse amd64 Packages 100 /var/lib/dpkg/status
