Nagios Support Forum

After installing Nagios, I am no longer able to update via yum or dnf. It looks like a bunch of dependency errors on packages associated with the install. Any ideas on how to fix? NagiosXI is installed vie rpm so that we can manage and deploy with automation.

Looks like this is similar to 60711

Did you install the nagiosxi package manually from an RPM you downloaded from our offline repo, or did you configure yum to use the nagios repo?

There are some extra steps needed to make the repo work for Cent8. Namely:

We configured Yum to use the Nagios repo. To be clear, the install works and we get a working version of Nagios. I have repeated this process several times. The problem is that we can no longer run a yum update due to packages in the Nagios repo. No amount of flushing or resetting yum or dnf fixes the issue.

What are the outputs from the following commands: It's odd... the Centos 8 Nagios repo should let you upgrade to nagiosxi-5.7.5. Maybe something is broken with how the repo is configured.
