Can not install required Docker rpm packages 

Cause

Docker is conflicting with the container-tools module in Rocky Linux. This module contains the Podman tool, which is incompatible with Docker and both of these tools can not be installed on the same system.

Resolution

Remove the container-tools module:

1. Log in to the server via SSH

2. Run either of the following commands:

# dnf remove @container-tools

OR

# yum remove runc podman
