UPDATE: 

根据@aldanux 的建议:

According to @aldanux suggestions:

    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.

roberto@ubuntu:~/keys$ ssh -i ec2-key-pair.pem [e-mail]
Warning: Permanently added the ECDSA host key for IP address '54.72.242.0' to the list of known hosts.

推荐答案

试试这个步骤:

ssh-keygen -R 54.72.242.0

sudo chmod 600 ec2-key-pair.pem

然后:

ssh -i ec2-key-pair.pem [e-mail]
