前言
Debian使用國外鏡像源，在國內使用會造成更新軟件慢或者找不到等問題，裝完系統，應對軟件源進行設置，改爲國內源，下載速度就變快。
阿里源：
- 打開站點 https://opsx.alibaba.com/mirror
- 找到debian相關內容，點開右邊debian使用幫助頁面
- 複製源地址到剪切板

需要哪個系統的則自行替換對應版本
操作步驟
以阿里源爲例子，自行替換所屬源
- 設置源
# 切換到root權限下
cp /etc/apt/sources.list /etc/apt/sources.list.bak # 備份原有文件
# 打開文件編輯
vi /etc/apt/sources.list
# 替換內容爲剛纔複製的內容
deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib

deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main

# 保存並退出
- 更新操作
# 配置好之後更新軟件包列表
apt-get update
# 升級系統所有軟件
apt-get upgrade
# 升級系統版本
apt-get dist-upgrade
忠告
不要同時配置多個源，同一倉庫的源啓用一個即可，否則容易引起混亂。
