I reluctantly filed that bug report. Why reluctant? Because I think the person or persons actually having the problem should file the bug report.
Edit: This won't work because of missing dependencies so don't bother.
Try removing all virtualbox and vbox packages. But first write down all the packages you are removing. Then manually download corresponding 5.1.10 packages from here. Don't forget to install corresponding Extension Pack from here. There are 2 versions listed. They are identical except for label so doesn't matter which you select.
If there any errors let me know. I'm going to try this myself in my 2014 partition when I get some time.
Edit: Also reluctant to file a bug report on this because I don't have time to do justice to the ones I already have on file.
