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:/..................
Please contact your system administrator.

解决

这段信息说的是key已经变了，但主机里的key还是旧的，这时候输入如下命令删除目标服务端ip的key：

shell 复制代码

ssh-keygen -R 192.168...(your target IP)

然后再用ssh连接一次重新输入密码即可。
