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 ECDSA key sent by the remote host is

具體情況是挖垛，之前家里的二奶開發(fā)機(jī)裝的是ubuntu 16.04爽蝴，已經(jīng)使用終端連接過，系統(tǒng)存有指紋備份昧辽，發(fā)現(xiàn)不一樣了，不允許連接登颓，解決辦法是搅荞。
右鍵Finder，前往文件夾框咙，/Users/你的用戶名
打開終端咕痛，輸入 defaults write com.apple.finder AppleShowAllFiles -bool true，再按com + alt + esc喇嘱，選中Finder重啟茉贡，就可以看到.ssh隱藏文件夾了，右鍵它者铜，在新的finder里面打開腔丧，然后編輯文檔known_hosts，刪掉之前此ip留下的那一串作烟，然后就可以鏈接了愉粤。
