Steps to reproduce:

1. Create new Rocky9 VM, run yum update
2. Install mariadb-server
3. Follow official installation instructions at https://www.zabbix.com/download for Zabbix 6.0LTS / Rocky 9 / Server, Frontend, Agent / Mysql / Apache
4.  

Result:

This command:

{{{{dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent }}}}

fails to fulfil dependencies and gives this error:

Error: 
 Problem: package zabbix-web-deps-6.0.10-release1.el9.noarch requires zabbix-web = 6.0.10-release1.el9, but none of the providers can be installed
  - cannot install both zabbix-web-6.0.10-release1.el9.noarch and zabbix-web-1:6.0.8-1.el9.noarch
  - package zabbix-apache-conf-6.0.10-release1.el9.noarch requires zabbix-web-deps = 6.0.10-release1.el9, but none of the providers can be installed
  - package zabbix-web-mysql-1:6.0.8-1.el9.noarch requires zabbix-web = 1:6.0.8-1.el9, but none of the providers can be installed
  - cannot install the best candidate for the job
(try to add '-allowerasing' to command line to replace conflicting packages or 'skip-broken' to skip uninstallable packages or '-nobest' to use not only best candidate packages)

Running the command again with option --nobest allows package installation to complete with these out-of-sync versions:

[root@zabbix ~]# rpm -qa zabbix-web
zabbix-web-6.0.10-release1.el9.noarch
[root@zabbix ~]# rpm -qa zabbix-web-mysql
zabbix-web-mysql-6.0.10-release1.el9.noarch

I cannot determine yet if these different versions of packages work correctly together

Expected:

All Zabbix components should successfully resolve with their dependencies, either version 6.0.8 or 6.0.10, which ever is newest
