在我的 CentOS 8 服务器上，许多 dnf和 yum命令失败并出现此错误:

Failed to download metadata for repo

这似乎仅适用于涉及 https 连接的存储库，例如:

/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
...

我用过 wget测试到这些站点的连接性并且它是成功的，例如 wget https://mirrors.fedoraproject.org成功。

然而，各种 dnf或 yum命令失败:

$ dnf provides /bin/ls
Extra Packages for Enterprise Linux Modular 8 - x86_64     0.0  B/s |   0  B     00:00
Failed to download metadata for repo 'epel-modular'
Error: Failed to download metadata for repo 'epel-modular'

我该如何解决这个问题？

Answer 1

就我而言

sudo rm -r /var/cache/dnf 

解决了我的问题。
