Github: Permission denied (publickey) but I got "You've successfully authenticated" message

Question

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 git@github.com: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 git@github.com

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 git@github.privateRepo/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? — ChrisGPT was on strike, Jun 13 '15 at 11:30
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, Jun 13 '15 at 14:39
When you say you're trying to clone `privateRepo/repo.git`, `privateRepo` should be a *user* or *organization*, not a repository. Something like `git@github.com:user/project.git` is more accurate. Are you doing that? — ChrisGPT was on strike, Jun 13 '15 at 15:10
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, Jun 13 '15 at 15:28
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. — ChrisGPT was on strike, Jun 13 '15 at 16:02
Yes. I had the message, and I selected Yes. As you see my log above, the authentication is success when I run the debug. However when I try to clone with ssh it just not allowed. Something weird just happened — Tom Kim, Jun 13 '15 at 16:36

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.

After doing `ls -la` I found that by creating folder from FTP its username is different and from command prompt it is different. Created folder by FTP then its worked correctly. – mujaffars Feb 26 '16 at 12:04
can you elaborate on "I need to set the correct folder permission for current user"? What exactly did you do to resolve the problem? – FuzzyTree Jul 18 '16 at 18:12
e.g I am login as tom, I need to set the owner of the folder become tom – Tom Kim Jul 21 '16 at 08:21

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.

Open your terminal and run the below command step by step

$ ssh-add -l -E sha256
You will get something like this

256 SHA256:CMY4Hfwu5CPf0xxxxx/kzsluFSyr7HhkL2b5XXXXX email@example.com (ED25519)
Go to .ssh directory

~$ cd ~/.ssh
Run this command with your id (ED25519)

$ cat id_ed25519.pub
You will get something like this (I have altered the key) ssh-ed25519

AAAAC3NzaC1lZDI1NTE5XXXXINN9c+lXXXXXXQd1sSo2I4trq6rD/2lbBd3OrYPDoG email@example.com
Copy the entire thing from point 5
Open your github account -> go to setting -> SSH and GPG Key
Click on new SSH key button
Paste your complete key from point 5 and add any title in SSH

and you are done!!!
