Great, so glad it worked out, and thank you for contributing your process, this is exactly what I needed!
I’m building a full Home Assistant Core .deb package with dh-virtualenv, so we can all leave this confusion behind and just install with pkg i homeassistant, so your process is really useful to see. I’ll review and merge with my build script.
There are known issues with network reconnects triggering an error loop (socket _accept_connection() error 22), and a discovery bug that relies on /etc/resolv.conf. I have patches for both in the pipeline, but for now you may want to use a restart automation.
Will share once I have something working.
