Finally I can confirm, that the @Jean-Baptiste Lallement's idea work... 😎😉 I have download the buggy artful upgrader from "http://archive.ubuntu.com/ubuntu/dists/artful-updates/main/dist-upgrader-all/current/artful.tar.gz", manually extract its content and apply proposed path to "DistUpgradeController.py". After that everything is done and I already have Ubuntu Artful (17.10) upgraded and working. At time of this post writing, upgrader version (timed 2017-10-31 17:48) is still the buggy one. It's time the path to be applied in "artful.tar.gz", so automatic upgrade to be possible through update manager (not by hand, like me, at least for other people). @Jean-Baptiste Lallement THANKS FOR YOUR WORK!
