无法安装软件包 rpms，它尝试了多个镜像并最终失败。这个问题是从昨天开始发生的，之前它工作正常，不确定 repomd.xml 文件中发生了什么变化。还有其他人面临同样的问题吗？

这似乎是一个更广泛的已知问题，与文件timestamp内部与属性repomd.xml不同的revision属性有关。

目前的建议如下：

  • 打开/etc/yum.repos.d/epel.repo文件。
  • 注释掉该metalink属性。
  • 取消注释该baseurl属性。

执行此操作后，运行yum clean metadata或yum clean all.

这应该只在短期内完成，一旦问题得到解决，就会恢复。

看起来 CentOS 软件包存储库中存在问题。

作为一种解决方法，您可以epel-release手动下载软件包并使用以下命令进行安装；

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