Debian10切换镜像源

Debian 的软件源配置文件是 /etc/apt/sources.list。
将系统自带的该文件做个备份，将该文件替换为下面内容，即可使用 TUNA 的软件源镜像。

如果遇到无法拉取 https 源的情况，请先使用 http 源并安装：

$ sudo apt install apt-transport-https ca-certificates

备份Debian默认的源地址

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup 

执行vim /etc/apt/sources.list将下方代码替换原来的代码：

 

vi /etc/apt/sources.list

gedit /etc/apt/sources.list

 

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security buster/updates main contrib non-free

修改好后执行sudo apt-get update更新源

sudo apt-get update
