Permission denied (publickey) from ec2 to github

Question

Please note: I first log in into my ec2 server with ssh.

Then I created a new ssh key. Generating it gave me these files:

id_ed25519.pub
id_ed25519

I opened the setting page at github and added a new ssh-key. I entered the content of "id_ed25519.pub".

I go back to my ec2 instance and run this command:

git clone git@github.com:myusername/myrepo.git

What I get is this error:

Permission denied (publickey).

If I run this:

ssh -Tv git@github.com

then I get this message:

Hello username. You've successfully authenticated, but GitHub does not provide shell access.

Why am I not able to clone the repo?

Answer 1

Assuming you are running ssh -Tv git@github.com from the same ECS environment you are attempting your clone, said clone should work.

You can compare the ssh -Tv git@github.com output (which works) with your git clone by doing:

export GIT_SSH_COMMAND='ssh -Tv'
git clone git@github.com:myusername/myrepo.git

You will see if the git clone use attempting to use the same keys as your ssh did.
