Permission Denied (publickey) AWS

Question

I know this is one FAQ. But I am new to this. I went through all the given solution out there. But nothing seems to solve my problem

Following will explain you better.

ssh -v -i xxxxx-ec2.pem ubuntu@ec2-xx.xx.xx.xx.us-west-2.compute.amazonaws.com

I am getting

Actually by mistake I deleted the xxxxx.pub which was in the home/ubuntu folder when I was trying to rectify the above problem. But I generated a .pub file using

ssh-keygen -y 

then just pasted the .pub file back into folder /home/ubuntu/ via SFTP . Please help me.

Answer 1

you need to add the new content of the .pub in /home/ubuntu/.ssh/authorized_keys or /home/ubuntu/.ssh/authorized_keys2.

Another way to do that is to use ssh-copy-id
