Now I’m having a hard time uninstalling the Pushover Paper UI action; the circling arrow gets stuck and it never finishes. Tried the force uninstall described here (bundle:uninstall <ID>), then restarted the openHAB service via sudo systemctl restart openhab2.service and I still can see the Pushover action listed as installed. Should I just ignore Paper UI and copy the jar you pointed me to into the openHAB-share\openhab2-addons folder?
