I'm getting this on a SL 7.4 machine:

/etc/cron.daily/0yum-daily.cron:

Update notice SLBA-2017:2087-1 (from sl-security) is broken, or a bad
duplicate, skipping.
You should report this problem to the owner of the sl-security repository.
If you are the owner, consider re-running the same command with --verbose to
see the exact data that caused the conflict.
