2023-03-23 - GitHub问题：远程主机标识已更改

Question

今天我尝试从/向我的常规GitHub存储库fetch，pull或push代码时，遇到了以下错误：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Host key for github.com has changed and you have requested strict checking.
Host key verification failed.

我苦苦思索如何解决它，以及它的根源在哪里。

希望他们昨天已经发布了一篇关于它的文章！

长话短说，这是你问题的答案：

ssh-keygen -R github.com
curl -L https://api.github.com/meta | jq -r '.ssh_keys | .[]' | sed -e 's/^/github.com /' >> ~/.ssh/known_hosts

但不要盲目相信我，可以看一下博客文章： https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/

也许在这里镜像新正确密钥的指纹会很有用：SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s（但显然要在文章中进行双重检查！） - Joachim Sauer
