1、下載64位的raspbian

下載安裝時注意你的派是否支援64位

https://downloads.raspberrypi.org/raspios_arm64/images/

2、換成國內源（親測是可以支援64位的源）：

把/etc/apt/sources.list所有內容替換為：

deb http://mirrors.tuna.tsinghua.edu.cn/debian buster main contrib non-free
deb http://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
 

deb http://mirrors.tuna.tsinghua.edu.cn/debian buster-updates main contrib non-free
# Uncomment deb-src lines below then 'apt-get update' to enable 'apt-get source'
#deb-src http://mirrors.tuna.tsinghua.edu.cn/debian buster main contrib non-free
#deb-src http://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
 

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

然後在把/etc/apt/sources.list.d/raspi.list所有內容替換為：

deb http://mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui
 

4.更新

sudo apt-get update
sudo apt-get upgrade
