I am trying to install virtualbox. I istalled it and then the
virtualbox-dkms module. The problem is that the modules was installed
but not loaded.

I have /lib/modules/5.18.0-4-amd64/updates/dkms/vboxdrv.ko

When I run modprobe on it I get this error:

  modprobe: FATAL: Module vboxdrv not found in directory
      /lib/modules/5.16.0-0.bpo.4-amd64

I tried to point modprobe to this the directory where the module was
located, but it didn't hava any effct.

I should point this out:

$ nano /etc/devuan_version
daedalus/ceres

even though in sources.list is

deb http://deb.devuan.org/merged chimaera main non-free contrib
deb http://deb.devuan.org/merged unstable main contrib non-free

I probably ran # update without having remembered the second line was
present.
