先备份 /etc/yum.repos.d/fedora.repo 和 /etc/yum.repos.d/fedora-updates.repo
将 fedora-ustc.repo 和 fedora-updates-ustc.repo 放入 /etc/yum.repos.d/ 中.
运行：
sudo dnf makecache


Fastestmirror

在dnf配置文件 /etc/dnf/dnf.conf 中添加fastestmirror=true即可启用fastestmirror。启用后在下载时会有（类似）提示 determining the fastest mirror (14 hosts).. done.表明已经启用fastestmirror。还有，根据 dnf.readthedocs.org/en/latest/conf_ref.html默认情况下fastestmirror的值为false。
