Git Error: Permission Denied (publickey) - How to Fix

The error message 'Permission denied (publickey)' suggests that you lack the necessary permissions to access the repository or that the repository doesn't exist.

To resolve this issue, consider the following steps:

1. Check access rights:

   • Ensure you are logged into the correct GitHub account.
   • Verify if you have the necessary permissions for the repository. For private repositories, you might need to be added as a collaborator.

2. Verify repository existence:

   • Double-check the URL of the repository you're trying to clone.
   • Confirm that the repository has been created and is accessible on GitHub.

3. Ensure correct SSH key usage:

   • If you're using SSH for GitHub authentication, make sure the SSH key linked to your account is correctly set up.
   • Verify that the public key is added to your GitHub account. You can check this in the 'SSH and GPG keys' section of your GitHub account settings.

If you encounter persistent issues, reaching out to the repository owner or administrator for assistance may be helpful.
