如何修复树莓派在更换了一个 SD 系统卡后，无法使用 SSH 登录问题 All In One

known hosts

Raspberry Pi 无法 SSH 登录，报错 ❌

/Users/xgqfrms-mm/.ssh/known_hosts

ssh pi@raspberrypi.local

$ ssh pi@raspberrypi.local
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ED25519 key sent by the remote host is
SHA256:OSm7xD6bEquDahA8bP4syFSsZNgUpsg70HfiSuj5A8Q.
Please contact your system administrator.
Add correct host key in /Users/xgqfrms-mm/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/xgqfrms-mm/.ssh/known_hosts:6
Host key for raspberrypi.local has changed and you have requested strict checking.
Host key verification failed.

solution

# 查看
$ cat /Users/xgqfrms-mm/.ssh/known_hosts



# 修改/删除
$ sudo code  /Users/xgqfrms-mm/.ssh/known_hosts

# $ sudo vim  /Users/xgqfrms-mm/.ssh/known_hosts
# $ sudo nano  /Users/xgqfrms-mm/.ssh/known_hosts

raspi-config

# GUI 交互式命令行界面
$ sudo raspi-config

在本质上还是直接修改 /boot/config.txt 配置文件
