@    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 RSA key sent by the remote host is
SHA256:xxxxxxx.
Please contact your system administrator.
Add correct host key in /Users/xxx/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/xxx/.ssh/known_hosts:1
Host key for github.com has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Solution

执行如下命令，找到输出中 github.com 对应的 IP 地址。

1

ssh-keygen -lf ~/.ssh/known_hosts

比如：

1

256 SHA256:xxxxxxxxxxxxxxxx github.com,13.250.177.223

对找到的 IP 地址（e.g. 13.250.177.223），执行：

1

>>>> $ ssh-keygen -R 13.250.177.223

完成！执行成功后会有如下输出：

1

3


# Host 13.250.177.223 found: line 1
/Users/xxx/.ssh/known_hosts updated.
Original contents retained as /Users/xxx/.ssh/known_hosts.old

再执行 git 或 ssh 命令时会有如下提示，输入 yes 即可。

Are you sure you want to continue connecting (yes/no)?
