我正在尝试使用 SSH 连接到我的 EC2 实例，但我快疯了。我已阅读这篇文章并尝试了所有用户组合:
AWS ssh access 'Permission denied (publickey)' issue
它仍然不适合我。知道我错过了什么吗？

UPDATE:
根据@aldanux建议:
roberto@ubuntu:~/keys$ ssh-keygen -R 54.72.242.0
# Host 54.72.242.0 found: line 4 type ECDSA
/home/roberto/.ssh/known_hosts updated.
Original contents retained as /home/roberto/.ssh/known_hosts.old
roberto@ubuntu:~/keys$ ssh -i ec2-key-pair.pem ec2-user@ec2-54-72-242-0.eu-west-1.compute.amazonaws.com
Warning: Permanently added the ECDSA host key for IP address '54.72.242.0' to the list of known hosts.
Permission denied (publickey).
最佳答案
您可能以错误的用户身份登录。如果它是 Ubuntu 实例，命令将是:
ssh -v -i ec2-key-pair.pem ubuntu@ec2-54-72-242-0.eu-west-1.compute.amazonaws.com
