@ 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:□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□
Please contact your system administrator.
Add correct host key in /c/Users/ryo/.ssh/known_hosts to get rid of this message.
Offending RSA key in /c/Users/ryo/.ssh/known_hosts:2
RSA host key for bitbucket.org 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.
PS D:\dev\hogeこんな時は既に保存してあるキーを削除すればOK
known_hostsを直接編集してもいいし、ssh-keygenコマンドのRオプションでもよし
以下はssh-keygen -Rで削除した例
PS D:\dev\hoge> ssh-keygen -R bitbucket.org
# Host bitbucket.org found: line 2
/c/Users/ryo/.ssh/known_hosts updated.
Original contents retained as /c/Users/ryo/.ssh/known_hosts.oldこれでgit pushすると知らんサイトだけどつないでいいか?言われるんでyesっていうと新しいキーが登録されて無事pushできました
PS D:\dev\hoge> git push
