docker安装报错：docker-ce conflicts with 2:docker-1.13.1-208.git7d71120.el7_9.x86_64

一、问题描述

安装docker的时候报错

运行:
yum -y install docker

报错：
...

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

二、问题原因

新安装的docker和系统中已经安装的docker-ce和docker-ce-cli版本有冲突，删除冲突包即可。

三、解决办法

解决问题办法：

sudo yum -y remove docker-ce
sudo yum -y remove docker-ce-cli
