The bugtracker is for reporting a bug. All requests for help should be sent to ​https://forums.virtualbox.org

Unless you are manually installing/building Xorg and XFree86 you need to install with the --nox11 tag because server installs don't have DT's. Still all you will achieve is shared folders and not much else.

I still think this is a bug. Using "--nox11" did not solve the problem:

administrator@ubuntu:~$ sudo /media/cdrom/VBoxLinuxAdditions.run --nox11

Please note that I've been installing Guest Additions in Ubuntu Server without any options without issue using many earlier versions of VirtualBox.

You have set up your guest system to require signed kernel modules. That is something that we do not currently support, so you will need to either disable it or take care of it yourself.

Same problem, I'm using virtualbox with this VM since version VBox 3 without any problem. (And no I'm not using secureboot, My VM have not UEFI but Bios) It was working with latests GuestAddition from 5.1 but after upgrading to 5.2.6, I'm unable to run Xorg and I've this fail when building the additions.

@M.Poil
I don't believe that this is the same problem. Try to disable 3D acceleration. Also, take a look at #17463, I have a feeling that this might be your problem.
