启用 RPM Fusion 软件源
安装 Fedora 时会提示你是否启用其他第三方软件源。
但是自动启用的软件源，只有英伟达驱动程序、谷歌 Chrome 和 Steam 等软件源，全套的 RPM Fusion 软件源并没有自动启用，因此还有诸如 VLC 和 MPV 等软件也不可用。
建议你还是开启全套的 RPM Fusion，国内玩家还是建议使用清华的镜像开启 RPM Fusion：
sudo yum install --nogpgcheck https://mirrors.tuna.tsinghua.edu.cn/rpmfusion/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.tuna.tsinghua.edu.cn/rpmfusion/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
安装成功后，修改 /etc/yum.repos.d/ 目录下以 rpmfusion 开头，以 .repo 结尾的文件。具体而言，需要将文件中的 baseurl= 开头的行等号后面链接中的 http://download1.rpmfusion.org/ 替换为 https://mirrors.tuna.tsinghua.edu.cn/rpmfusion/， 替换后的文件类似如下：
