当我安装Docker时出现错误

Question

我已经安装了Docker，它运行得非常好。我现在正在尝试安装Centos操作系统，但是我一直收到错误提示。错误如下：

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

Transaction check error:

尝试使用版本号进行安装。我认为它与版本号冲突。docker-ce-18.06.1.ce-3.el7.x86_64 与 docker-ce-cli-0:18.09.0.ce-1.1.beta1.el7.x86_64 包中的文件冲突。 - Arun Kumar G R

问题似乎在于已安装的 docker-ce-cli 版本为 18.09.0.ce-1.1.beta1.el7，比您尝试安装的 docker-ce 包版本 18.06.1.ce-3.el7 要新。这样会导致 docker-ce 包无法正常安装。

在安装 docker-ce 包之前，您需要降级或删除 docker-ce-cli。
