Steps to reproduce:
- make a satellite server or local mirror of the packages
To get the correct key - unpack zabbix-release package, get the key information, could not verify if this key is official or not, because repo.zabbix.com provides several keys
For example, only one page is available for RHEL with some topic not related to the package verification: https://www.zabbix.com/documentation/6.0/en/manual/installation/install_from_packages/rhel_centos
Separate page where all the used/revoked keys (if any) are listed.
