Why can't I ssh-copy-id to an EC2 instance?
I needed to run
I had the same problem:
ssh-copy-id gives the error
Permission denied (publickey) on an AWS EC2 instance. I was sure that I set all the permissions correctly using
In addition, I needed to change this line in
I guess that's because
ssh-copy-id asks for your password.
Then the error disappeared.
It seems like ssh-copy-id is confused about connecting with a key in order to copy another key.
ssh-copy-id -f "-o IdentityFile ec2-keypair.pem" [email protected]
-o IdentityFile ec2-keypair.pem: I'm using a "raw" ssh option to connect using the AWS-generated key.
-f: ssh-copy-id tries to copy the AWS-generated key again, so force mode is necessary to copy the other key.
scp -i ec2-keypair ~/.ssh/id_rsa.pub [email protected]:~/
ssh -i ec2-keypair [email protected]
And when you logged in:
cat id_rsa.pub >> .ssh/authorized_keys rm id_rsa.pub exit
Now you can log with
ssh [email protected]

I'm a founder/hacker, who has gone from having touched any code since 2007. My first startup was founded in 2003 and I was in retrospect using alot of "worst of breed" technologies and methodologies. I learned from my mistakes and the heartache it caused, and am determined do it right this time. In the last 6 months I have learned and heavily used the following technologies: Ruby, Padrino, Objective C, MacRuby, Mongo DB, Chef, AWS, Elastic Search, Redis, Haml Soon to come: SASS, coffeescript, d3 This site has been INVALUABLE to the learning process and I am forever indebted to everyone who has helped me.Updated on September 18, 2022

I have a ubuntu Natty instance on EC2, and I can SSH into it by
ssh -v -i ec2-keypair [email protected]@XXXX.compute-1.amazonaws.com
But I'd like to set up password less sshing. So I tried these options and nothing is working:
$ ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected] Permission denied (publickey). $ ssh-copy-id -i ~/.ssh/ec2-keypair [email protected] /usr/bin/ssh-copy-id: ERROR: No identities found $ ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected] Permission denied (publickey).
