1 前言

一个问题，一篇文章，一出故事。
本章将解决Ubuntu系统从国内源安装或者更新的问题。

2 最佳实践

2.1 创建国内源配置

cp /etc/apt/sources.list.d/ubuntu.list /etc/apt/sources.list.d/ubuntu.list.save
vim /etc/apt/sources.list.d/ubuntu.list

加入如下配置，

deb https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse

# deb https://mirrors.aliyun.com/ubuntu/ noble-proposed main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ noble-proposed main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse

2.2 更新源配置

apt update
