我安装了 Fedora 16。通过 yum 更新和安装软件时，它会给出一些错误/警告。
Could not retrieve mirrorlist http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-16&arch=x86_64
error was 14: HTTP Error 404 - Not Found: http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-16&arch=x86_64
Error: Cannot find a valid baseurl for repo: rpmfusion-free
答案1
最近迁移了一些后端服务器。如果我没记错的话，出现了暂时中断的情况。
请尝试yum clean all并重试。
答案2
我以前遇到过这个问题。只需卸载/安装 rpmfusion repo 即可。
sudo yum remove rpmfusion-free-release rpmfusion-nonfree-release
然后
sudo yum install rpmfusion-free-release rpmfusion-nonfree-release
