(5) 更新下载源,使用命令
vi /etc/apt/sources.list
打开source.list文件,然后把里面的内容替换成以下内容,
deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian stable main contrib non-free
deb http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free
# deb http://mirrors.ustc.edu.cn/debian stable-proposed-updates main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian stable-proposed-updates ma
然后保存退出,使用命令apt-get update更下源,如图:
