No more output after changing autograding-image to ubuntu:18.04

[etwasanderes2]

What I did:

Changed the ubuntu version in the Dockerfile for the autograding image to 18.04.
I also needed to install sudo, as it is required by autodriver/Makefile.
Dockerfile.txt

Expected Behavior:

I should get the hello-world output.
Makefile.txt
expected-output.txt (actual output with ubuntu 16.04)

Actual Behavior:

I don't get the output that should be caused by the Makefile.
actual-output.txt
Note that Autodriver: Job exited with status 0 is missing.

Logs and debug information.

Ubuntu 16.04 still works.
