Resolved Unable to reinstall modsecurity after upgrade from Onyx to Obsidian

[Abernathy]

Server operating system version

CentOS Linux 7.9

Plesk version and microupdate number

18.0.57

In the process of upgrading to Obsidian, I had this conflict ;

Exception: Failed to solve dependencies:
plesk-modsecurity-configurator conflicts with mod_security-2.9.2-centos7.19091318.x86_64

I did remove mod_security thinking I would reinstall it after upgrade.
Maybe I should have used the installer to remove the component.

Complete!

Upgrade went fine afterwards and I now have Plesk Obsidian v18.0.57

My issue is that I cannot reinstall modsecurity.​

plesk installer --select-release-current --install-component modsecurity

Error

Can someone please help me to reinstall modsecurity ?

Found the problem... exclude=mod_security in /etc/yum.conf
I commented out that line and modsecurity install went fine.
