If the system tells you that there’s no adsb-setup.service, then this isn’t a ADS-B Feeder Image.
I’d start with a fresh SD card. I’d install directly from the image that is offered inside the Pi Imager. And I recommend to SKIP ALL CUSTOMIZATION. You are connected via Ethernet (at least that’s what I saw above in the thread), so leave the image unchanged and wait for it to come up. And then configure it over the web.
