我正在尝试在Centos LAMP服务器上安装phpAdmin并继续陷入同一点，这是一个存储库错误。我是linux的noob，不知道我错过了什么。我一直在使用liquidweb
中的以下内容以下是我收到的错误消息。

其中一个已配置的存储库失败（未知）， 并且yum没有足够的缓存数据来继续。此时唯一 百胜可以做的安全事情就是失败。有几种方法可以解决＆＃34;修复＆＃34;这样：
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
无法检索存储库的metalink：epel / x86_64。请验证其路径，然后重试＆＃34;
