简述
Armbain默认使用的是国外的软件源，但是速度很慢，安装软件下载速度韩漫，所以我们需要更换为国内源
操作
查看版本【可略】
Armbian上查看系统版本
cat /etc/armbian-release
例如：
root@armbian:~# cat /etc/armbian-release
# PLEASE DO NOT EDIT THIS FILE

操作步骤
打开 /etc/apt/sources.list 文件以编辑，将当前的软件源地址注释或备份，以便将来可以恢复到原始设置
sudo nano /etc/apt/sources.list
将以下内容【任选其一即可】添加到 sources.list 文件中：
