/root/src/oref0/lib/oref0-setup/device.json. That is part of the initial install of the master branch and it never gets to a complete install with the cron notices. I'm not sure which version of jubilinux is on the pi, but I think maybe if I get that 0.4.0 version flashed it might fix this. I'm going to give that a go now
Here's where I would change a step:
https://openaps.readthedocs.io/en/latest/_images/pi-curl-success.png << this picture at the end says Press Enter to run oref0-setup with the current release (master branch) of oref0, or press ctrl-C to cancel.
I would press ctrl-C, pull the developer branch of oref0.
cd ~/src/oref0 && git checkout dev && git pull
npm run global-install
cd && ~/src/oref0/bin/oref0-setup.sh
rm -rf ~/go/bin/*
