It would be very helpful if you could provide consistent URLs for your latest PMS downloads. Something like https://downloads.plex.tv/downloads/plexmediaserver_latest_amd64.deb.
Having this would greatly simplify installation on headless linux systems. It would also simplify automated installation scripts (ex. Docker Dockerfiles) for building. I'm noticing a very, very bad thing happening where community provided Dockerfile scripts are being provided that get the pms install from their site to simplify access. Making it easier to get this directly from you would be the first step in cleaning this up.
