VirtualBox complains about non-matching guest utils

[ottok]

While booting up the latest v20201205.0.0 box, I saw this:

==> wordpress-box: Checking for guest additions in VM...
    wordpress-box: The guest additions on this VM do not match the installed version of
    wordpress-box: VirtualBox! In most cases this is fine, but in rare cases it can
    wordpress-box: prevent things such as shared folders from working properly. If you see
    wordpress-box: shared folder errors, please make sure the guest additions within the
    wordpress-box: virtual machine match the version of VirtualBox you have installed on
    wordpress-box: your host and reload your VM.
    wordpress-box: 
    wordpress-box: Guest Additions Version: 5.2.8_KernelUbuntu r120774
    wordpress-box: VirtualBox Version: 6.1

Maybe the Guest Additions should be updated to VirtualBox 6.1? I wonder if they are backwards compatible, will they work with VirtualBox 6.0 or 5.2?

PR #58 would be one way to do it. Another option would be install VB Guest additions from a Bionic repo.

Status: this was fixed for a while and then it was broken again. Still a valid issue.
