virtualbox.org

I installed VB 6.1.14 under Debian Buster on my Dell laptop.
Starting a virtual Windows machine I get the message

Kernel driver not installed (rc=-1908)

In the message it says I should sign four modules: vdoxdrv, vboxnetflt, vboxnetadp, and vboxpci.
The first three modules are in '/usr/lib/modules/4.19.0-10-amd64/misc' and I was able to sign them.
But there is no module 'vboxpci'. Where do I get that from?

K.D.J.

vboxpci doesn't exist anymore on 6.1.x but the message was not yet updated.

OK, but what do I have to do to solve the problem of the not installed kernel driver?

Install dkms if not already and try

To the best of my understanding, official Virtualbox from www.virtualbox.org no longer requires dkms. If that package is needed, then it is likely that you're running the Linux distro's fork of Virtualbox.

To confirm/deny this, right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

You are correct. I checked the 2015 version of the documentation and it specifies the need for dkms - quoted below. The current documentation does NOT. May have to test it out sometime as I blindly install dkms on installs.

From 2015:

The VirtualBox kernel module is automatically installed on your system when you install VirtualBox. To maintain it with future kernel updates, for those Linux distributions which provide it -- most current ones -- we recommend installing Dynamic Kernel Module Support (DKMS). This framework helps with building and upgrading kernel modules.
