Best way to full uninstall and reinstall?

Hello. I’ve recently installed gitea and have run into an issue where I can create repos but accessing them gives me HTTP error 500 (a/k/a the least useful error). I have it running on a rpi 4B, raspbian 10. The pi also runs pi-hole and does so without a GUI: I do all management via ssh and the respective apps web interfaces. I’ve installed gitea via source (because getting docker running was like whoa not easy). I’ve deleted all the gitea* directories and files in my home dir and have stopped and removed gitea.service. Might I be missing anything?

Second, what would be the most user-friendly way to reinstall and get it running?
