树莓派在国内更新软件源很慢，可以更换为国内的软件源。

树莓派在国内更新软件源很慢，可以更换为国内的软件源。

1、更新/etc/apt/sources.list

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bk
sudo nano /etc/apt/sources.list

替换为以下内容（或者注释之前的，然后追加）

# ARM(32位系统)
deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ bullseye main contrib non-free rpi
# deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ bullseye main contrib non-free rpi

# ARM64(64位系统)
# Arm64 架构的 Raspberry Pi OS 仍处于 beta 状态，中科大源亦不含此架构。对于 arm64 的 Raspberry Pi OS，可以直接使用 arm64 Debian 的源（以 Bullseye 示例）：
deb https://mirrors.ustc.edu.cn/debian/ bullseye main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian bullseye main contrib non-free
deb https://mirrors.ustc.edu.cn/debian/ bullseye-updates main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian bullseye-updates main contrib non-free
deb https://mirrors.ustc.edu.cn/debian-security bullseye-security main contrib non-free
# deb-src http://mirrors.ustc.edu.cn/debian-security/ bullseye-security main non-free contrib

2、更新/etc/apt/sources.list.d/raspi.list

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

替换为以下内容（或者注释之前的，然后追加）

# ARM(32位系统)
deb https://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ bullseye main
#deb-src https://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ bullseye main


# ARM64(64位系统)
deb https://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ bullseye main
#deb-src https://mirrors.ustc.edu.cn/archive.raspberrypi.org/debian/ bullseye main

3、更新

依次输入以下命令进行更新。

sudo apt update && sudo apt dist-upgrade

如果需要单独更新EEPROM可以参考：传送门

如果apt update出现错误：The following signatures couldn't be verified because the public key is not available: NO_PUBKEY xxxxxxxxxxxxxxxxxxx

使用以下命令添加KEY：

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com xxxxxxxxxxxxxxxxxxx
