I ran into this problem recently (Sept 2017) trying to install Guest Additions into Oracle VM VirtualBox Manager version 5.1.28, in a newly-installed VM for Ubuntu version 16.04.3. The host is Win-10. The problem was that the Guest Additions CD image was already mounted. To fix it:
- In the VM Manager under Settings->Storage, under Controller: Right-click on VBoxGuestAdditions, and select “Remove Attachment." There will be a confirmation box: click “remove.”
- Click the “+” icon next to “Controller," to add new optical drive. A dialog box will open. Choose “Leave Empty-> Okay”
- Open the VM and select Devices->Insert Guest Additions. It should install now. Power off the VM (not the VM Manager) and restart the VM. GuestAdditions should now be working.
