It fails on RUN pybombs -v auto-config And here are the ruamel versions installed in the container

$ dpkg -l | grep ruamel
ii  python-ruamel.ordereddict  0.4.9-1                       amd64        dictionary that keeps keys in insertion resp. sorted order
ii  python-ruamel.yaml         0.10.23-1                     amd64        roundtrip YAML parser/emitter (Python 2 module)

$ pip list | grep ruamel
ruamel.ordereddict (0.4.9)
ruamel.yaml (0.10.23)

That is a pretty old version of ruamel.yaml. After setting up your ubuntu 16.04 you should upgrade ruamel.yaml (and pip and virtualenvutils). Preferably you should use a virtualenv in which to do so (i.e. intall virtualenv in your system Python, then create the virtualenv, update its pip, and then install other packages).

ruamel.yaml 0.10 should have the round_trip_load() call, though. Hmm.....

I've dropped < 0.15 support so I don't think this still applies.
