ssh/known_hosts 中的公钥与服务器的不匹配发生了异常错误;

解决办法

首先,通过终端移除本地 ssh 中现有异常的密钥

cd ~/.ssh/
ssh-keygen -R github.com 

其次,打开 known_hosts 添加 
GitHub 的 SSH 密钥指纹 并生成新的密钥

vi ~/.ssh/known_hosts
// 打开编译器后,输入 i
// 添加如下 ssh 密钥条目 
// github.com ssh-rsa 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
// 添加完成后 ESC 
// 最后保存退出 :wq

最后,重新尝试链接进行验证即可

ssh -T [email protected]
