Why installing this package ? On Rocky 8, dnf install nc install nmap-ncat package. Are you sure on your installation, ncat is absent ?

Positively.

Can you disable EPEL on your Redhat and retry please ? I think the netcat package from EPEL is installed instead of nmap-ncat.

netcat is provided from EPEL:

[root]# dnf info nmap-ncat | egrep 'Repository|From repo'
Repository   : appstream-8
[root]# dnf info netcat | egrep 'Repository|From repo'
Repository   : @System
From repo    : epel-8-x86_64

So I think we should install the package nmap-ncat instead of nc. The nmap-ncat package is available for Centos 7 too. Please remove nc package and replace it with nmap-ncat. This way the package will correctly be installed even if EPEL is enabled for RHEL 7 and 8.
