I am running Ubuntu 18.04.03 x64 Gnome-flashback, kernel 5.0.0-25-generic, and VirtualBox 6.0.10 r132072 (Qt5.9.5). After the latest software upgrade, I cannot launch any of my VM's. I get the following messgae:
RTRinitEX 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


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.
I ran the following with the results shown:
sudo /sbin/vboxconfig
[sudo] password for butch: 
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
What do I need to do to fix this?
