Permission denied (publickey). when connecting to AWS sever
i just spun up an AMI with amazon and I'm able to SSH in just fine using the key created by amazon. I've added a user to the system and set their password and when I try to log in i get "Permission denied (publickey)." when connecting to the server.

I know that normally its a permissions problem in this situation but I've checked those and they seem fine.. also given that i can ssh -i blah.pem in .. i'm guessing it may be a different issue? here is the sshd_config

the user is not a super user..but does have sudo access.
I assume you mean that you cannot log in to this new user using a password.
First you need to check that ssh_config allows users to log in using a password. Depending on your default setup it may not be a default option.
Also if your new user has superuser permissions, it may also be blocked from loggin in using a password.
UPDATE:
You need to set one or both of these to yes. I don't remember the second, so try the first one.
ChallengeResponseAuthentication no
PasswordAuthentication no
I'm not clear if you are trying to log in with or without a password. If you are trying to log in with a new user account and no password, you need to add the public key for your user to the .ssh
directory authorized_keys
file.
If your user is named 'spoofy', go to
/home/spoofy/.ssh/
and here create a file called authorized_keys
with your public key in it.
Then you should be able to log in with
$ ssh spoofy@ec2-#####.amazonaws.com
I have a longer writeup here.

this worked for me:
ssh-keygen -R <server_IP>
to delete the old keys stored on the workstation also works with instead of
then doing the same ssh again it worked:
ssh -v -i <your_pem_file> ubuntu@<server_IP>
on ubuntu instances the username is: ubuntu on Amazon Linux AMI the username is: ec2-user
I didn't have to re-create the instance from an image.
You may have to run restorecon
in the system
restorecon -r /home/*/.ssh
use super user or try command in root account.
example :
su ssh -v -i /path/key.pem username@IP_machine
