RPi配置国内软件源

先使用官方源进行一次update

查看系统版本(非常重要)

注意不要使用不是你系统版本的软件源

lsb_release -c

换源

sudo nano /etc/apt/sources.list
deb https://mirrors.ustc.edu.cn/raspbian/raspbian/ buster main contrib non-free
deb-src https://mirrors.ustc.edu.cn/raspbian/raspbian/ buster main contrib non-free
#deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
sudo nano /etc/apt/sources.list.d/raspi.list
