ssh 報錯Host key verification failed 或Ubuntu connect to serve 失敗

ssh 報錯Host key verification failed  或Ubuntu connect to serve 失敗  一般是由於沒有裝ssh

sudo apt-get install  openssh-server 就能夠了，可是我這邊是由於以前連上了，後面遠程服務器改了密碼，

以前保存的密碼驗證失敗，這時候就要把保存的密碼刪掉，哪裏刪掉？？？

用Ubuntu connect to serve 就直接報錯，用ssh就報下面的錯，

ssh xxx@xxx.xxx.xxx.xxx

其實，只要打開 /home/xxxxx/.ssh/known_hosts ，把23行的刪掉就能夠，那個是密鑰保存的，以後遠程登陸從新輸入新的密碼就能夠了
