Please guide me how to fix it.

Is this system behind a proxy server?

If so make sure you have the following modifications specifically to the yum.conf
https://support.nagios.com/kb/article.php?id=147

No, it is not behind any proxy server, system is on it's separate infrastructure VLAN and did do successful update of December 2017 and no changes have been made to network since then.

I tried manual upgrade and received following message:
