在 GitLab 中使用 SSH 进行 Git 克隆不起作用

Question

I have set my public ssh rsa key on my GitLab profile setting. And on my remote server I already add my ssh private key with

ssh-add ~/.ssh/id_rsa

In fact, when I run ssh connection verification on my remote server it is authenticated:

user@some-remote-server:/var/www$ ssh -T git@gitlab.com
The authenticity of host 'gitlab.com (xxx.xx.xxx.xx)' can't be established.
ECDSA key fingerprint is SHA256:anmsdaskdnaslkdmaskd.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'gitlab.com,xxx.xx.xxx.xx' (ECDSA) to the list of known hosts.
Enter passphrase for key '/home/user/.ssh/id_rsa':
Welcome to GitLab, @alramdein!
user@some-remote-server:/var/www$

And I'm the Owner of the repository. But when I run git clone it said fatal: Could not read from remote repository.

user@some-remote-server:/var/www$ sudo git clone git@gitlab.com:repo/repo.git
Cloning into 'repo'...
git@gitlab.com: Permission denied (publickey,keyboard-interactive).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
user@some-remote-server:/var/www$

Answer 1

You are using sudo git clone ; that means you aren't using the same ssh-agent than in your user.

If you want to check that, you can just perform

ssh-add -L

and

sudo ssh-add -L

And you will see that there isn't the same agent in both accounts.

I don't know why do you want to do git clone with sudo rights, but then you'll need to start your agent with sudo (for the root user) and attach the private key to it.

Also, since sudo disables the environment variables, you'd have to provide the SSH_AUTH_SOCK and the SSH_AGENT_PID each time you use ssh .
