Hello there,
None of this help has worked for me either and I'm having the same issues starting a VM...
What I haven't tried yet is executing the given command, well, I have but coming from Debian derivatives I run 'sudo /sbin/vboxconfig' with a 'command not found' as a return, so yes, I do need to get a fish manual and it would be nice if someone could point me in the right direction.
As I said before, I have tried both the arch and the dkms version with the same disappointing result.
Kind regards and thanks in advance.
