Guide for Seafile Pro on Proxmox VM

I’ve read through several forum posts and installation guides and I’m confused about how I should about installing SeaFile Pro on a Proxmox VM.

This seems to be the best one I find but it’s for 18.04, any issues considering 20.04/10 is available?

This guide is for 20.04 but only SeaFile CE, should it work for Pro too?

Does this script work well?

I’m also confused about how to work the nginx component as I’m already running nginx as a reverse proxy on a different VM for all my other servers. Should I be using both nginx instances?
