Rob as an FYI I've used your setupUbuntuSBC.sh script to do the setup on the ODROID M1. It seemed to run pretty well. I'm having an issue with a package upgrade but that is not related to your stuff. No real life observatory control as yet but solves ran nicely. I don't seem to have icons in the Ekos control buttons (I've seen that often but have not quite worked out what it is caused by).
Thanks again for your work in setting those scripts up.
