数霉派4buster系统更换镜像源

系统自带的源实在太卡了。于是更换。

备份源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bk　　　　
或者直接注释掉原来源（在前面加＃）

使用nano编辑器更改文件/etc/apt/sources.list

sudo nano /etc/apt/sources.list  


#中科大
deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ buster main contrib non-free rpi

#阿里云
#deb http://mirrors.aliyun.com/debian buster main
#deb http://mirrors.aliyun.com/debian-security buster/updates main
#deb http://mirrors.aliyun.com/debian buster-updates main

#清华
deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib
deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib

按住ctrl＋w，再输入y，回车保存退出。下同

更新/etc/apt/sources.list.d/raspi.list

 sudo nano /etc/apt/sources.list.d/raspi.list


#中科大
deb http://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ buster main

#清华
deb http://mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui

最后更新一下源：

sudo apt update
