Git Permission denied (public key) but public key is added and working

Question

Hello I am facing issue to use git push origin master or git pull origin master because my remote origin is using SSH to connect, I have already setup SSH key pair configurations I also check this solution but it is not working for me. To test connection I issued following command on Ubuntu

ssh -T git@github.com

and it shows the following message

Hi zain! You've successfully authenticated, but GitHub does not provide shell access.

I am confused if my authentication is working with the SSH test command then why it is not working with push or pull procedure

Error is following

git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

yup . but wait a min why do i need a user when using ssh authentication? — Zain Ul Abidin, Jun 04 '21 at 09:40
Did you start the ssh-agent and load the private key using ssh-add? — kometen, Jun 04 '21 at 09:41
No i did not because i mapped the ssh key in config file so i assume it is loading correct private file . — Zain Ul Abidin, Jun 04 '21 at 09:45
Check [the documentation](https://docs.github.com/en/enterprise-server@2.22/github/authenticating-to-github/troubleshooting-ssh/error-permission-denied-publickey) for troubleshooting tips? — evolutionxbox, Jun 04 '21 at 09:47

Make sure your remote URL is actually using that .ssh/config entry, and the right private key.

Try:

GIT_SSH_COMMAND='ssh -Tv' git push

And see what exact key is used.

If you have a .ssh/config like:

Host gh
  Hostname github.com
  User git
  IdentityFile ~/.ssh/mykey

Your URL should be:

gh:<me>/<myrepo>

loading correct private file

An ssh-agent is only needed of your private key is passphrase-protected, and has nothing to do with the ~/.ssh/config file .
