Debian apt 换源#

使用说明#

警告
操作前请做好相应备份。

一般情况下，将 /etc/apt/sources.list 或 /etc/apt/sources.list.d/debian.sources 文件中 Debian 默认的源地址 http://deb.debian.org/ 替换为 http://mirrors.ustc.edu.cn 即可。

可以使用如下命令：

1
sudo sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
2
sudo sed -i -e 's|security.debian.org/\? |security.debian.org/debian-security |g' \
3
      -e 's|security.debian.org|mirrors.ustc.edu.cn|g' \
4
      -e 's|deb.debian.org/debian-security|mirrors.ustc.edu.cn/debian-security|g' \
5
      /etc/apt/sources.list

1
sudo sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list.d/debian.sources

目前使用 DEB822 格式的 Debian 分发仅有容器镜像，且其安全更新源默认设置为 http://deb.debian.org/debian-security，因此以上命令会同时替换 Debian 官方源和安全更新源。

提示
[什么是 DEB822 (.sources) 文件格式？]
自新版本的 Debian 与 Ubuntu 起，例如：

Debian 12 的容器镜像

Ubuntu 24.04

默认预装的系统中 APT 的系统源配置文件不再是传统的 /etc/apt/sources.list。传统格式（又被称为 One-Line-Style 格式）类似如下：
1
deb http://mirrors.ustc.edu.cn/debian/ bookworm main contrib
新的 DEB822 格式自 APT 1.1（2015 年发布）起支持，后缀为 .sources，存储在 /etc/apt/sources.list.d/ 目录下，格式类似如下：
1
Types: deb
2
URIs: https://mirrors.ustc.edu.cn/debian
3
Suites: bookworm
4
Components: main contrib
5
Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg
在切换软件源时，需要根据实际情况选择对应的格式进行修改。
关于 DEB822 格式的设计考虑，可以参考官方文档（英文）。

当然也可以直接编辑 APT 源文件（需要使用 sudo）。以下是参考配置内容：
