I have Icinga running on an Oracle Linux 7 (a RHEL 7 clone) root server. Automatic updates are configured with yum-cron. Lately there has been a batch of Icinga-related updates. Since then I get the following warning:
Outdated schema version: ‘1.14.3’. Latest version: ‘1.15.1’.
What exactly is the problem here? And what can I do about it?
