我知道这是一个常见问题。但我是个新手。我研究了所有给定的解决方案。但似乎没有什么能解决我的问题
下面会更好地解释你。
ssh -v -i xxxxx-ec2.pem ubuntu@ec2-xx.xx.xx.xx.us-west-2.compute.amazonaws.com
我得到

事实上，当我试图纠正上述问题时，我错误地删除了主/ubuntu文件夹中的xxxxx.pub。但我使用生成了一个.pub文件
ssh-keygen -y
然后通过SFTP将.pub文件粘贴回文件夹CCD_ 3中。请帮帮我。
您需要在/home/ubuntu/.ssh/authorized_keys或/home/upuntu/.sh/authorized_keys2中添加.pub的新内容。
另一种方法是使用ssh复制id
