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:~
Please contact your system administrator.
Add correct host key in /Users/niege/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/niege/.ssh/known_hosts:2
RSA 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.
- 이전 키를 제거한다.
ssh-keygen -R github.com

ssh-keygen -R github.com
# Host github.com found: line 2

- 새 RSA SSH 공개키 항목을 추가한다.
ssh-keygen -R github.com
curl -L https://api.github.com/meta | jq -r '.ssh_keys | .[]' | sed -e 's/^/github.com /' >> ~/.ssh/known_hosts
이때 'zsh: command not found: jq' 라고 뜬다면, jq를 따로 설치해주어야 한다.
brew install jq
- 다시 푸시해본다.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Are you sure you want to continue connecting (yes/no)? yes
- Warning이 발생한다면 Warning: the ECDSA host key for 'github.com' differs from the key for the IP address '00.200.000.000'
