Today's Ubuntu update helped fix this for me. I had to run the following to finish setting up...
$ sudo apt-get install virtualbox-dkms $ sudo modprobe vboxdrv
Download: 'VirtualBox 6.1.16 Oracle VM VirtualBox Extension Pack' from https://www.virtualbox.org/wiki/Downloads
* If it doesn't install automatically, add to VirtualBox > File > Preferences > Extensions
