I am unable to install Nagios XI on a RHEL 7 server

========================
Nagios XI Full Installer
========================

This script will do a complete install of Nagios XI by executing all necessary sub-scripts.

IMPORTANT: This script should only be used on a 'clean' install of CentOS or RedHat. Do NOT use this on a system that has been tasked with other purposes or has an existing
install of Nagios Core. To create such a clean install you should have selected ONLY the 'Base' package in the OS installer.

The script that failed was: './0-repos'

This appears to be a known issue with RHEL, did you check with your vendor?

Apparently one of the causes is incorrect system date.

Now I am seem to be getting this error

I should probably mention that this is a VM on AWS. this is an EC2 instance. this is a fresh install

[root@usvanagiosdev8 nagiosxi]# ./fullinstall

Have you tried adding the Optional channel? It is required.

This issue is described in the following KB article:
https://support.nagios.com/kb/article/e ... tions.html

Yes, tried that

Does the AWS host have internet access? Mine do not. Just wondering...

What is the output from:

attached

Yes, it does have access to the internet

Doesn't look enabled. What was the full output from when you ran: Have you reached out to your OS vendor on how to enable their own repositories?
You can print the available list like this: or check here:
