I had system updates break UCPNode tonight. The CLI procedure to remove and reinstall didn’t work.
I ended up uninstalling and reinstalling it via Modules Admin. Several dependencies and their dependencies have to be disabled for this to be done. First disable Zulu. Then Sangoma CRM. Then SMS and WebRTC. That’s three separate steps. Then uninstall User Control Panel, reinstall it, and reverse the process to re-enable the disabled modules.
