I have installed Archbang linux in a virtual machine in a macOS host (running High Sierra). The installation went fine but when I try to insert the VBoxGuestAdditions (which I guess I need to get full screen), I get the following error:
I'll be grateful for any tips.Unable to insert the virtual optical disk /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso into the machine archbang.
Could not mount the media/drive '/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
