My system has stopped sending “updates are available” notifications since I updated from 7.6.1810 to 7.7.1908.
Please see my support post here:
I get other notification emails from failed cron jobs, but
/etc/cron.daily/0yum-daily.cron does not send any notifications.
I’m currently manually checking the software center for updates.
The system should send an “updates are available” notification when updates are available.
