Running the suggested /sbin/vboxconfig accomplished nothing--I still get the error.RTR3InitEx failed with rc=-1912 (rc=-1912)
The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing
'/sbin/vboxconfig'
may correct this. Make sure that you are not mixing builds of VirtualBox from different sources.
where: supR3HardenedMainInitRuntime what: 4 VERR_VM_DRIVER_VERSION_MISMATCH (-1912) - The installed support driver doesn't match the version of the user.
The installation procedure I followed is found here: https://www.virtualbox.org/wiki/Linux_Downloads
But what is REALLY disturbing is that after uninstalling 6.0.10 and re-installing 5.2, I get the same error. Which means I can't use Virtualbox any more on this host.
I'm willing to live with 5.2; can someone point me in the direction of getting either version to work?
