linux - 在 Centos 7 上安装 EPEL 存储库会破坏 yum 功能吗？

所以我正在尝试设置一个 ssh 堡垒服务器，但我在设置 EPEL 以安装 Python3.6 时遇到问题。

我正在使用 CentOS Linux release 7.4.1708 (Core)

所以我尝试先安装 EPELsudo yum -y install epel-release(我当然做过 sudo yum -y update 之前它工作正常)，但它告诉我 Package未找到“epel-release”

因此我尝试了使用 RedHat Package Manager 的不同方法:

sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

这会成功安装包，我可以在 etc/yum.repos.d 中看到 epel.repo 和 epel-testing.repo (我在帖子末尾复制了它们的内容)

但是，现在，每当我尝试用 yum 做一些事情时，无论是更新还是安装某些软件包，它都会给我以下错误(例如我使用 yum -y install Python3.6或者我也尝试安装 tsclient 或 python-pip):

[root@scw-39016b yum.repos.d]# yum install -y Python3.6

base                                                     | 3.6 kB     00:00

Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=armhfp error was
No repomd file


 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     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

File /var/cache/yum/armhfp/7/epel/metalink.xml does not exist

我已经尝试了数百万种方法来解决这个问题，但似乎没有任何帮助:(

我重新安装了大约 5 次，我已经完成了 sudo yum clean all，我尝试取消注释 baseurl 并在 repo 文件中注释 metalink还有其他方式，等等......，但没有任何帮助:(

谁能告诉我，是什么导致了这个错误？

我在某处读到它可能与启用/禁用某些存储库有关，但我不知道如何处理它..

非常感谢!!!
