Hi Folks!                                            March 29. 2018

Just had an issue with a one of the Ubuntu Updates clobbering my
VirtualBox -- great! there goes the BBS and ILink!!

Error messages included:

  - Virtualbox kernel module not match; try 'modprobe vboxdrv'
    (Didn't appears to do anything except to return to Terminal
    immediately.)

  - RTR3InitEx failed with rc=-1912 (rc=-1912).  The installed support
    driver doesn't match the version of the user.  (I've heard about
    these cryptic error messages on Macs!)

  - Error: NS_Error_Failure (0x80004005)  (So the 80004005 code says to
    go to Sun's website and download the Linux installer.  I don't want
    to clobber what had been working!)

So rebooted.  SOS.

Rebooted and went back to the previous version (the new and improved
everything except VirtualBox was 4.4.0-116, went back to 4.4.0.112.
That got the SOS too.  Grr.

Rebooted to go back to the current version; not sure if I want to try to
fix or wait for a correct that may not occur: had looked around the web
for a simple and non-destructive fix; the issue has popped up for
several years, with dozens of proposed corrections, so of which stated
works, others stated did not work.  Among them:

  - sudo modprobe vboxdrv  ==> the original trial was without sudo.
    This trial worked as well as the original.

  - sudo apt-get update
    sudo apt-get install --reinstall virtualbox
    Got the same errors.
    
Fiddle-fiddle, search, search.  Dawns on me there's potentially a step 
missing, so:
    sudo apt-get update
    sudo apt-get upgrade
    
Was going to go on with with the --reinstall step but decided to check, 
maybe because I had noticed a 'response line' re: 'virtualbox dkms' 
scroll by.  VirtualBox works (yeaaaa!!) and did upgrade as the screen 
looks slightly different.

Hopefully this can help someone else.
