I just installed a fresh copy of Debian 8.4 in VirtualBox 5.0.20.
I am now attempting to install the "Guest Additions" CD. To do so I had to change my fstab so I am able to execute things from the CD, so this is already fixed.
But now I get the following error:
root@debian:/media/cdrom# ./autorun.sh Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: The connection is closed
Can someone please help?
