Running vbox on my ubuntu 16.04 TLS laptop with no issues for a couple of years now. Today, when I try to start one of my vm's, I get this:
So, following the instructions there:
ed@ed-Gazelle-00:~$ sudo /sbin/vboxconfig
[sudo] password for ed:
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.
There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root.
contents of the log file:

The man page for make says nothing about 'oldconfig' or 'prepare', and doing a little googling about it what I find sounds like it can be pretty dangerous to your system if you don't take a lot of precautions.
Advice?
