Resolving the Issue: Git Clone with SSH in GitLab Doesn't Work

When you're trying to clone a repository from GitLab using SSH and encounter issues, it can be frustrating. Many users have faced the same problem: after adding their public SSH RSA key to their GitLab profile, they find that the cloning operation fails with a "could not read from remote repository" error. In this post, we'll dive deep into this problem and lay out a clear solution to get you back on track.

The Problem

You've set up your SSH public key in your GitLab profile and verified that your SSH connection to GitLab works seamlessly. Yet, when you attempt to clone a repository using the command:

you receive a permission denied response from GitLab. It can leave you confused, especially since you're the owner of the repository.

Understanding the Issue

The key point to understand here is that using sudo changes the user context under which the command runs. This affects how the SSH agent interacts with your key. When you run sudo git clone, you're not accessing the same SSH agent that you set up with your user credentials. As a result, the SSH keys that have been loaded into your agent are not available to the sudo command.

Verification Steps

To confirm the issue, execute the following commands to see if the SSH keys are loaded correctly:

If the outputs differ, then you're indeed accessing different SSH agents, which is the root of your problem.

Solution: How to Properly Clone the Repository

Avoid Using sudo with Git Clone

The best practice is to avoid running Git commands with sudo unless absolutely necessary. Running git clone as a standard user helps keep the SSH agent context in sync.

If You Must Use Sudo

In some cases, you might have to use sudo. If so, follow these steps to make it work:

Start an SSH Agent as Root:
Run the SSH agent using sudo:

Add Your Private Key:
You'll need to add your SSH private key to the root's SSH agent:

Set Environment Variables:
Since sudo disables environment variables, ensure to export SSH_AUTH_SOCK and SSH_AGENT_PID. For example:

You can find the correct values by running these as a normal user before invoking sudo.

Re-Attempt the Clone Operation

Now, try running the git clone command again as root. If the setup is correct, you should now be able to clone the repository without encountering permission issues.

Conclusion

Cloning a Git repository from GitLab with SSH can be straightforward if your SSH keys and agent configurations are properly aligned. Remember, it's best to perform Git operations without sudo where possible to avoid complications with different user contexts for SSH keys.

If you find yourself in a situation where sudo is necessary, carefully follow the outlined steps to ensure access to your SSH agent and keys.

With these solutions, you should be able to clone repositories confidently and smoothly. Happy coding!
