STDERR：yum-dump 存储库错误：无法检索存储库的存储库元数据 (repomd.xml)：epel。请验证其路径并重试

这一直是我的服务器的一个长期问题。我使用 EPEL 存储库来安装和升级nss包。但我经常遇到这个问题，它因错误而失败。

STDERR: yum-dump Repository Error: Cannot retrieve repository metadata (repomd.xml) for repository: epel. Please verify its path and try again

服务器/内核，rhel6.6：2.6.32-504.el6.x86_64

这/etc/yum.repo.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
enabled=1
failovermethod=priority
gpgcheck=1
gpgkey=http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
sslverify=true

我也有一台服务器，同样可以正常工作。未显示此问题的服务器在以下位置具有可用的存储库缓存：

/var/cache/yum/....

而引发错误的那个没有任何 epel 存储库缓存条目。

使用进行调试

URLGRABBER_DEBUG=1 yum upgrade nss 2> debug.log

PS：我已经审核过了这但在这种情况下它没有帮助。

这是我这边的本地网络问题吗？我可以访问服务器超时的网址。
