It turns out latest unity version for Linux is distributed using a download assistant; UnitySetup-2017.3.0p2. I did not try anything yet, but this may make it harder for the docker image to follow latest versions.

Thanks Brian for letting me know. Maybe some people at Unity will still provide deb files for releases later. Let's hope it won't kill this project. If someone has more details on this or ideas on how to get a deb or at least find a way to fully install Unity using command line with that sp2 file, please comment here 🍻
