安装命令：

登录可见。

错误原因：CentOS 8 默认安装了 podman 代替 Docker，containerd.io 和 podman 存在冲突。

Podman 是一个开源的容器运行时项目，可在大多数 Linux 平台上使用。Podman 提供与 Docker 非常相似的功能。正如前面提到的那样，它不需要在你的系统上运行任何守护进程，并且它也可以在没有 root 权限的情况下运行。

Podman 可以管理和运行任何符合 OCI（Open Container Initiative）规范的容器和容器镜像。Podman 提供了一个与 Docker 兼容的命令行前端来管理 Docker 镜像。

解决方案，执行如下命令：

登录可见。

从系统中移除一个软件包，其实最起初的命令应该是 erase，remove 是 erase 的一个别名。
