Linux Yum 已安装的包比需要的包版本更高的解决方法

Linux下使用yum安装软件包是，有时会提示已安装的依赖包比需要的包版本更高，yum安装软件时有类似下面的提示：

其实就是带(@updates)标志的是通过系统更新，打了更新补丁后，导致版本过高了，只要删除更新包就可以了，有2个方式可以解决：

1、yum downgrade尝试降级相关的包，比如：yum downgrade krb5-libs krb5-devel openssl-libs openssl glibc glibc-common  glibc-devel glibc-headers nscd libxml2 libxml2-devel libxml2-python

或者

2、将安装的软件包同步到最新的可用版本yum distribution-synchronization
