[gal_17]

Hi,
I want to upgrade zabbix to new version but have these errors:

 dnf upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agent
Last metadata expiration check: 0:26:01 ago on Mon 08 May 2023 09:55:35 AM CEST.
Error:
 Problem: cannot install the best update candidate for package zabbix-server-mysql-6.2.9-release1.el9.x86_64
  - nothing provides libevent-2.1.so.6()(64bit) needed by zabbix-server-mysql-6.4.2-release1.el8.x86_64
  - nothing provides libevent_pthreads-2.1.so.6()(64bit) needed by zabbix-server-mysql-6.4.2-release1.el8.x86_64
  - nothing provides libnetsnmp.so.35()(64bit) needed by zabbix-server-mysql-6.4.2-release1.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
​

When i add skip broken and nobest i get next errors:

Don't add '--skip-broken' or '--nobest', using either of those options is a mistake. I wish 'dnf' didn't suggest it at all, because the real fix is usually something else.

Look at the error messages you are receiving. Notice how some of them say things like:

- nothing provides ... needed by <something>.el8.x86_64

Or

[SKIPPED] zabbix-<something>.el8.x86_64.rpm

Those messages are telling you that you're trying to install packages built for CentOS 8 (el8 -> Enterprise Linux 8).

You likely have the wrong 'zabbix-release' package installed, because you definitely have some incorrect repositories defined.
