Rob I didn't end up with a functional system for some reason. I could not find kstars and the utilities scripts were missing as the most obvious bit's that failed. I do have a working x11vnc server. I don't know why the failures happened yet and am doing some play with what I have (installed kstars, building indilib from source etc) before restarting from a clean build with some extra logging running.
After an install of kstars some things started but Ekos failed trying to start up mount and ccd simulators.

I have most things running after some manual steps although Ekos crashes when I try and connect either of my ZWO ASI cameras.
Given how far I've got I might try the rebuild on the other box so I can keep playing while that runs.

Love what you have done here, I'm assuming it's an oddity with my setup .
