VUnit Docker Image not working

[albydnc]

I am trying to run my tests on ghdl/vunit images. Calling GHDL directly works, but both VUnit and Makefile fail.
Make output:

root@5ab5d015f669:/wrk# make file
ghdl -a --std=08  file_driver.vhdl
make: ghdl: Operation not permitted
make: *** [Makefile:14: file] Error 127

VUnit output:

root@466176e28305:/wrk/LHCbAurora# python3 run_ci.py *aurora_loopback_tb*

Re-compile not needed
