VirtualBox rcvboxdrv setup error "Bad argument setup"
From a comment on the ticket, run the following command:
sudo /usr/lib/virtualbox/vboxdrv.sh setup
instead of the command given by VirtualBox.
On the Oracle's bugtracker I found that the issue is already fixed in the "test" build: https://www.virtualbox.org/wiki/Testbuilds.
Ref: https://www.virtualbox.org/ticket/15055
Until this is fixed, you could edit the /sbin/rcvboxdrv
file (e. g. in a terminal using Nano editor via sudo nano /sbin/rcvboxdrv
) and add some lines:
[…]
while test -n "${1}"; do
case "${1}" in
--nostart)
START=
;;
# START Workaround for https://www.virtualbox.org/ticket/15055
setup)
/usr/lib/virtualbox/vboxdrv.sh setup
;;
# END
*)
echo "Bad argument ${1}" >&2
exit 1
;;
esac
shift
done
[…]
Use CTRL+O to save the changes. After this, you should be able to run sudo /sbin/rcvboxdrv setup
again.
