Freepbx not automatically downloading upgrades from 10.13.66-13 in Sysadmin pro

I have sysadmin pro, but my system is not upgrading from 10.13.66-13 to 14 or to 16. It just says upgrades in progress but it never finishes. Why would this be hanging and how can I get this to upgrade?

On rare occasions an update can hang. Unlock with:

/usr/sbin/sysadmin_update_system --unlock

I get the response update already in progress. Just hangs there

This is the update log file results:
