Good afternoon I am trying to install Docker on a Red Hat 8 and following the tutorial on the page:
https://www.linuxtechi.com/install-docker-ce-centos-8-rhel-8/
I find this error that I can't find with its solution, and it doesn't let me move forward
[root@srvdevrma1 ~]# dnf -y install docker-ce --nobest

As the OP comments, uninstalling this particular package resolves the issue via sudo yum uninstall podman
