1.将下面内容的添加入/etc/apt/sources.list（香港镜像）
#For software deb http://mirrors.ustc.edu.cn/debian/ stretch main deb http://mirrors.ustc.edu.cn/debian/ stretch-updates main deb http://mirrors.ustc.edu.cn/debian-security stretch/updates main #For wineHQ deb https://dl.winehq.org/wine-builds/debian/ stretch main #For driver deb http://httpredir.debian.org/debian/ stretch main contrib non-free
你也可以用一下命令：
echo "deb http://mirrors.ustc.edu.cn/debian/ stretch main deb http://mirrors.ustc.edu.cn/debian/ stretch-updates main deb http://mirrors.ustc.edu.cn/debian-security stretch/updates main deb https://dl.winehq.org/wine-builds/debian/ stretch main deb http://httpredir.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list
2.执行更新动作
apt-get update
注意：下面是163的debian9的源（会快些毕竟国内的）
deb http://mirrors.163.com/debian/ stretch main non-free contrib deb http://mirrors.163.com/debian/ stretch-updates main non-free contrib deb http://mirrors.163.com/debian/ stretch-backports main non-free contrib deb http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib
