@Cedric_Richardson welcome to Roonlabs forums.
Yeah, you’re right about it being a bit wild-west. I’m surprised to see Roon Moderators chiming in up there in the thread supporting the Original Post(er) with his Docker installation! So that’s a real boon.
I took a peek at the docker code in the steefdebruijn. One of the things about Dockers, they don’t actually need to be maintained unless they break, or stop working for some reason. The docker references
http://download.roonlabs.com/builds/RoonServer_linuxx64.tar.bz2
Which should be the latest version of Roon Server direct from roonlabs. But it pulls 1.7 build 537.
For posterity here are a couple of other threads that are worth checking out:
