我试图安装使用YUM安装shibboleth SP包（百胜安装shibboleth）。 安装时出现以下错误。

如果你的浏览器里有404， 那是什么意思 ？ 这里是一样的东西。
您已经caching了有关此存储库的元数据不再有效，或者您有networking问题到达镜像。 从yum clean all开始，再试一次。 如果仍然失败，请开始调查networking堆栈。 （你是否在这个主机上为download.opensuse.orgcaching了一个不好的DNSlogging）
最后我确定了这个问题。
我的机器联系的镜像不包含请求的文件。
因此，更改存储库configuration中的基本URL /镜像列表即可解决问题。
