Comment (by ooogwayduh-rock):

 '''Docker Toolbox''' installs VirtualBox as part of its run.

 '''
 https://github.com/docker/toolbox/releases
 '''

 Perhaps packages known to be broken and years out of date should stop
 early automatically with an informative message and alternatives.

 And, anyone curious to fix that package have the choice to force install
 then see how they go.
