I have a license for System Admin Pro. I am able to manually trigger updates without issue, and I have configured a weekly schedule for automatic updates on both of my systems; or so I thought. Unfortunately, neither of them have ever automatically updated.
You should see a cron task that does system updates, but you probably won’t. Ensure Systen Admin is up to date, and browse to Updates, resubmit the page with your update setting enabled, and then rerun the above command to confirm the cron task is now present.
I have tried this fix for FreePBX 14 / SNG 7 and I don’t have anything populated in my crontab. I even checked the crontab for the asterisk user and theres nothing in there about module / system updates.
