Hi, > This is probably because dkms failed in building.
Nope: $ sudo dkms status virtualbox, 5.1.30, 4.13.0-1-amd64, x86_64: installed In fact, "modprobe vboxdrv" works, as I indicated in my original email. After doing so, VirtualBox works fine. But something is wrong if I have to load the module manually. Could you please reopen? Kind regards, Ralf
