System Updates by Itself

Even though I have updates configured for manual, occasionally, the system will do some sort of automatic update.


/var/log/secure:

Hello, Check to see if /etc/cron.daily/0yum-daily.cron exists on your system. If so, you likely have the "yum-cron" package installed, which automatically updates your system packages: yum-cron(8) - Linux manual page Thank you.

I can't see this cron. I've not knowingly installed anything, in fact I prefer to do updates manually, so I can control how and when. Could there be anything anywhere else ?

Assuming the yum-cron RPM does not exist on your system, and automatic package updates are disabled in cPanel, I suggest opening a support ticket using the link in my signature so we can take a closer look. You can post the ticket number here so we can update this thread with the outcome. Thank you.

Support suggested commenting out a line in root cron. 0 2 * * * yum update -y >> /dev/null 2>&1 I'm assuming this is var/spool/cron/root ?

You can edit the root cron job while logged in as "root" with the following command:
crontab -e
It's stored at "/var/spool/cron/root". Note this is not a standard cron job. Thank you.
