树莓派Raspberry Pi OS安装与切换国内源系统安装系统镜像下载附官网地址 2. 下载balenaEtche

系统安装

系统镜像下载附官网地址
下载balenaEtcher进行系统镜像烧录
烧录完成后在boot盘中创建wpa_supplicant.conf文件连接wifi,或使用网线连接

country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="iPhone"
    psk="104104104"
    key_mgmt=WPA-PSK
    priority=1
}

创建ssh文件可进行ssh连接

树莓派开机后切换国内源

系统环境查询

cat /etc/os-release
uname -a

2. 修改/etc/apt/sources.list文件，注释原有源，并粘贴

sudo nano /etc/apt/sources.list

deb https://mirror.nju.edu.cn/debian/ bullseye main contrib non-free
deb https://mirror.nju.edu.cn/debian-security/ bullseye-security main contrib non-free
deb https://mirror.nju.edu.cn/debian bullseye-updates main contrib non-free

修改文件/etc/apt/sources.list.d/raspi.list

deb https://mirror.nju.edu.cn/raspberrypi/debian/ bullseye main

测试

sudo apt update
sudo apt upgrade

解决切换源问题

如果出现he following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9165938D90FDDD2E执行下列命令添加公钥即可

gpg --keyserver  keyserver.ubuntu.com --recv-keys 9165938D90FDDD2E
gpg --export --armor  9165938D90FDDD2E | sudo apt-key add -

2.出现Temporary failure resolving问题，修改/etc/resolv.conf文件如下
