I tried to install a fresh StaNogs raspbian on my new Pi 3B+. It didn’t start. Tried an aftermarket powersupply and an original RPi supply, but nope.
So I put the same card in my Pi 3B and everything was ok. After all was installed and updated/upgraded I took it and put it in the Pi 3B+ again and it WORKED.
Looks like some of the config, start or … stuff of SatNogs Raspbian is too old for the initial boot on the Pi 3B+.
Just did my first install with the new image you linked to and its running on a brand new Pi 3B+. As far as I can tell it is working. my site is “online” in testing mode. and I scheduled a few observations.
