遇到这个问题情景：
下午第一台系统是Centos7， 安装配置完成后，接着一台是Centos 6 系统，由于疏忽直接下载并安装了 “epel-release-7-5.noarch.rpm”，安装时提示了问题，于是下载安装“epel-release-6-8.noarch.rpm” ，安装成功后发现遇到 问题了”Error: xz compression not available”。
遇到问题的原因：
epel-release-75.noarch.rpm 进了cache目录
如何解决这个问题：
需要手动进行清理 cache, 然后重新remove当前的 epel-relase， 最后重装一下正常的“epel-release-6-8.noarch.rpm”即可。
所有操作如下：
