安装 Docker 时出现错误

Question

我已经安装了 docker，它工作得很好。我现在正在尝试安装 Centos 操作系统，但我不断收到错误消息。错误如下。

+ sh -c 'yum install -y -q docker-ce'

Transaction check error:

问题似乎是docker-ce-cli 的安装版本是18.09.0.ce-1.1.beta1.el7，它比您尝试安装的docker-ce 软件包的版本18.06.1.ce-3.el7 更新。 docker-ce 包装并没有为此做好准备。

在安装docker-ce 软件包之前，您必须降级或删除docker-ce-cli。
