Step I had done: https://help.github.com/articles/generating-ssh-keys/ follow exactly.

$ eval "$(ssh-agent -s)"
Agent pid 31944
$ ssh-add
Enter passphrase for /home/centos7/.ssh/id_rsa:
Identity added: /home/centos7/.ssh/id_rsa (/home/centos7/.ssh/id_rsa)

$ ssh-add -l
4096 ab:4d:23:23:99:ce:bb:9d:9f:9e:f9:b2:c8:1a:cd:f7 /home/centos7/.ssh/id_rsa (RSA)

However, when I run

$ git clone [email protected]:privateRepo/repo.git

Cloning into 'repo'...
The authenticity of host 'github.com (192.30.252.130)' can't be established.
RSA key fingerprint is 56:27:ac:a5:36:28:2d:36:23:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,192.30.252.130' (RSA) to the list of known hosts.

fatal: Could not read from remote repository.

Below is the output I run

$ ssh -Tv [email protected]

As the line above showed that Hi tomkim! You've successfully authenticated, but GitHub does not provide shell access. which means I already unthenticated, but why I can't clone my repo?

Update: I can clone in my home directory, but when I try with sudo it did not work, it happen in my /var/www/html/ folder

$ sudo git clone [email protected]/repo.git Cloning into 'repo'... Warning: Permanently added the RSA host key for IP address '192.30.252.131' to the list of known hosts. Permission denied (publickey). fatal: Could not read from remote repository.

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

I know I can clone with HTTPS, but I would like to solve this issue, anyone can help?

Are you trying to clone your own repository, or somebody else's? – Chris
Yes. I do try my own repo also can't. The above example is a private repo. The git clone does not work in ssh. – Tom Kim
When you say you're trying to clone privateRepo/repo.git, privateRepo should be a user or organization, not a repository. Something like [email protected]:user/project.git is more accurate. Are you doing that? – Chris
Yes. I am doing that. I try to clone my own repo also not working... could it possible centos 7 setting different? This is first time I work with centos7, my Mac is working fine... – Tom Kim
I don't think that CentOS is significant. Do you always get the "Permanently added the RSA host key for IP address '192.30.252.131'" message? It's in the output of both your ssh and git clone commands. – Chris

The answer is related user permission issue. I need to set the correct folder permission for current user.

For the git sudo issue, the answer can be found in below link:

https://help.github.com/articles/error-permission-denied-publickey/#should-the-sudo-command-be-used-with-git

Thanks Chris for looking into this question.

Copy your SSH public key under your SSH directory.

cd ~/.ssh
cat id_rsa.pub

Copy the pub key and paste it under "SSH and GPG key" under GIT "settings" page.

Click your profile photo --> "Settings" --> "SSH and GPG key" , Now add the Copied text.

use this https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/

then get your generated key ( start with ssh-rsa or other type ) go to your git user panel -> SSH & GPG Keys --> New SSH key -> paste your key ( fill title with any ) then press Add SSH key

Will Fix.

good luck.
