我在尝试更新 yum 以确保安全时出现以下错误，有人可以建议修复吗，我有运行 yum clean 元数据但没有用我担心运行ning yum clean all因为这被建议作为另一个 post 的修复，因为我不确定它的作用？

Answer 1

您应该删除 /etc/yum.repos.d/ 目录中的无效 repo 文件。

首先检测回购文件：

# grep -l apt.sw.be /etc/yum.repos.d/

删除无效的 repo 文件并清理 yum 缓存：

# sudo yum clean all

Answer 2

虽然 AliOkan 提供了一个有效的答案，但这是它首先失败的原因，因为我也遇到了类似的问题。

根据您的跟踪（顺便说一句，您实际上有一个 el5 引用，不再维护）：

此错误指出 RPMForge 存储库存在一些问题，然后在 official repo 上有此信息：

RPMforge/RepoForge status

RPMForge/RepoForge is a dead project. It is not maintained. DO NOT USE.

它不再正式维护，但如果需要，有镜像，请参阅上面的 git 问题。
