无法检索镜像列表http://httpupdate.cpanel.net/cpanel-plugins-clatest-x86_64-mirrorlist 错误是 14：HTTP 错误 404 - 未找到

配置的存储库之一失败（未知）， 并且 yum 没有足够的缓存数据来继续。此时唯一 百胜可以做的安全的事情是失败。有几种方法可以“解决”这个问题：

 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. Disable the repository, 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>

 4. 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

找不到 repo 的有效 baseurl：cpanel-plugins/latest/x86_64
