According to https://github.com/moby/moby/issues/4032#issuecomment-163689851 (and some other comments in the issue) it's not recommended to set `DEBIAN_FRONTEND` via `ENV` in a Dockerfile. `ARG` has the same effect at build time but does not change `DEBIAN_FRONTEND` in the final image, so I switched to it. It should also work to remove it completely.
