debian10 buster入坑指北-修改更新源

0. 使用的tuna更新源，可能需要先安装https支持

apt install apt-transport-https ca-certificates

1. 备份/etc/apt/sources.list

mv /etc/apt/sources.list /etc/apt/sources.list.bak

 2. 修改使用 TUNA 的软件源镜像

vi /etc/apt/sources.list

替换为以下内容

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

3. 检查更新

apt update

 4. 更新（已经部署好的环境慎用！）

apt upgrade

 

* 有些场景下可能需要恢复默认

# /etc/apt/sources.list

# deb cdrom:[Debian GNU/Linux 10.4.0 _Buster_ - Official amd64 DVD Binary-1 20200509-10:26]/ buster contrib main

deb cdrom:[Debian GNU/Linux 10.4.0 _Buster_ - Official amd64 DVD Binary-1 20200509-10:26]/ buster contrib main

deb http://security.debian.org/debian-security buster/updates main contrib
deb-src http://security.debian.org/debian-security buster/updates main contrib
