What is Troubleshooting “Permission Denied (publickey)” in Git?

This template focuses on addressing the error message 'Permission Denied (publickey)' that users may encounter while using Git for version control. This error often arises due to SSH key issues or misconfigurations, hindering access to remote repositories. Understanding how to resolve this error is crucial for smooth version control operations.

Understanding the Error

Resolving the Error

To troubleshoot this error, ensure that your SSH key is correctly generated, added to your SSH agent, and associated with your remote repository account. You may also need to verify your SSH configuration files for accuracy.
