GitHub SSH access not working

I have created a new user on github under our organization which will be used for auto deployment. I followed the article on

Somehow, when I tried to clone the repository to the server, it worked once. The code was running properly, and I exit the server. Today, we released an update to the code, and I wanted to deploy the code manually to the server, so I ssh'd into the server and tried to pull the repository with

git pull
. It gave me Permission denied error. After some debugging I realized that the ssh-agent wasn't running. So I executed the following commands:

eval "$(ssh-agent -s)"
ssh-add .ssh/id_rsa_staging

Now, when I try
ssh -T
, I see the welcome message which is:

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

But when I try to pull from the repository, I am continuously getting this error message:

Permission denied (publickey).
fatal: Could not read from remote repository.

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

I checked the repository and the user has read access to it. I double checked if the keys match on github and server, yes they do. I tried generating new keys. I tried using ssh/config file. Nothing helped...

I appreciate any help & suggestions!


So I figured out that
git clone
command is working properly, but even when I try
git pull
right after git clone, it is giving the error.

If you are using sudo to git pull/push to the remote you need to ensure you used sudo to generate your SSH keys. Otherwise you will not be using the same keys that you originally generated.
