Unable to insert the virtual optical disk /opt/VirtualBox/additions/VBoxGuestAdditions.iso into the machine Lubuntu .
Would you like to try to force insertion of this disk?
Could not mount the media/drive '/opt/VirtualBox/additions/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).
Geriau pasižiūrėję matom, kad 'Guest Additions' diskas jau uždėtas.
Sprendimas
Lubuntu Guest Additions instaliavimas:
$ sudo apt-get update && sudo apt-get install dkms
Dabar reikia nueiti į 'Guest Additions' direktoriją ir paleisti:
$ sh ./VBoxLinuxAdditions.run
