I have podman installed on a CentOS 8 machine. I want to switch to Docker so need to remove podman first because it conflicts with Docker. However, when I try to remove it I get this:
Error:
Problem: The operation would result in removing the following protected packages: dnf, systemd, systemd-udev
Tried this and it didn't work: https://www.ibm.com/docs/en/eam/4.2?topic=questions-troubleshooting-tips#uninstall_podman
buildah is not even installed
Tried with both yum and dnf - no go
solved by adding --allowerasing
sudo yum install docker-ce.x86_64 --allowerasing
