CentOS

Hi forum
I have a small server updated to CentOS Linux release 7.7.1908
Also installed yum-cron a long time ago.
Now it has started giving errors

Not using downloaded updates/repomd.xml because it is older than what we have:
Current : Thu Sep 26 22:31:21 2019
Downloaded: Thu Sep 19 04:37:30 2019

But when I run yum update from the cli, it completes as expected.

No packages marked for update

TIA's for any clues how to fix this unwanted error.

These hourly error messages by email have become irritating.
Will disable this service (or the error messaging) until there's a fix.

Try sudo yum clean all
