window 下在用putty ssh 登入虛擬機器的ubuntu的時候報錯 如下：

To solve the issue, open the configuration for the connection and navigate to SSH -> Kex. In the “Algorithm selection policy”, move the “Diffie-Hellman group 14” entry to the first position in the list.

解決這個問題，只需要開啟putty的 configuration 在connecttion->SSH->kex中，將 “Algorithm selection policy” 中的  “Diffie-Hellman group 14”
