1、CentOS下Extmail的搭建关于Error: xz compression not available2015-05-30 23:562067人阅读评论(0)举报找到原因是安装软件时错误安装了CENTOS 7版本的软件导致yum不可用。附上原文：Your fix removes the repository entirely. The correct fix is to remove the cached files for epel under /var/cache/yum/epel and to uninstall the EPEL *7* version of the rpm wh
