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

2. 原因分析：

1. 我这次测试使用的docker镜像是，网易云提供的基础 centos 镜像，该版本是 centos:6.7

   	https://c.163yun.com/hub#/library/repository/info?repoId=1055
   

   	FROM hub.c.163.com/public/centos:6.7
   

2. CentOS 6已经随着2020年11月的结束进入了EOL（Reaches End of Life），官方便在12月2日正式将CentOS 6相关的软件源移出了官方源，随之而来逐级镜像也会陆续将其删除。

3. 不过有一些老设备依然需要维持在当前系统，CentOS官方也给这些还不想把CentOS 6扔进垃圾堆的用户保留了各个版本软件源的镜像，只是这个软件源不会再有更新了

3. 解决方法：

复制运行以下代码：

sed -i “s|enabled=1|enabled=0|g” /etc/yum/pluginconf.d/fastestmirror.conf
mv /etc/yum.repos.d/CentOS-base.repo /etc/yum.repos.d/CentOS-base.repo.backup
curl -o /etc/yum.repos.d/CentOS-base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo
yum clean all
yum makecache
