yum / dnf错误：无法下载用于回购的元数据 [英] yum/dnf error: Failed to download metadata for repo

问题描述

在我的CentOS 8服务器上，许多 dnf 和 yum 命令失败，并显示以下错误：

On my CentOS 8 server, many dnf and yum commands fail with this error:

无法下载用于回购的元数据

Failed to download metadata for repo

这似乎适用仅用于涉及https连接的存储库，例如：

This seems to apply only to repositories involving https connections, e.g.:

/etc/yum.repos.d $ cat epel-modular.repo
[epel-modular]
name=Extra Packages for Enterprise Linux Modular $releasever - $basearch/pub/epel/$releasever/Modular/$basearch
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-modular-$releasever&arch=$basearch&infra=$infra&content=$contentdir
...

我已经使用 wget 测试与这些站点的连接，并且成功，例如 wget https://mirrors.fedoraproject.org 成功。

I have used wget to test connectivity to these sites and it is successful, e.g. wget https://mirrors.fedoraproject.org succeeds.

但是，各种 dnf 或 yum 命令失败：
