So - "finally" got the Pi back on the web. But in the process of troubleshooting I removed nginx, switched back to Apache, and also uninstalled everything #Pleroma. Yes, now that I figured out the problems I *could* reinstall it. But, damn that feels like a lot of work after all the headache I just went through. It's bad enough being my own sysadmin for a couple of web sites. But Pleroma is all Elixir/Erlang/Phoenix/all kinds of shit I am completely unfamiliar with. I think I'm good for now...
@donblanco In case you change your mind, I wrote up my own install experiences here: https://github.com/wimvanderbauwhede/limited-systems/wiki/Mastodon-and-Pleroma-on-the-Raspberry-Pi-3
@donblanco No problem, it was just in case. I'm glad you've read it anyway.
@wim_v12e I have read your page and utilized it before. Thank you. Still, unlikely I'll change my mind. Too many other things to occupy my time these days...
