Description

Update the procedure for adding third-party ssl certificates in Amazon Linux 2 with version 4.4 and higher. https://documentation.wazuh.com/current/user-manual/wazuh-dashboard/configuring-third-party-certs/ssl.html

As of Wazuh OVA 4.4, Amazon Linux 2 is being used as base image, which does not support many epel-release packages, and one of them is snapd, which would be the next package to install according to the guide. The procedure for such Amazon linux should be corrected.

If you do it according to the current procedure you get the following message:

yum install epel-release
Loaded plugins: langpacks, priorities, update-motd
No epel-release package available.
Error: Nothing to do

This issue was found while testing the OVA, but the documentation is generic for all the installation methods. I will move it to another project.
