Resolving cPanel Git Error Code 128: ‘Permission Denied’ Issue

Introduction

In cPanel, a lot of users could encounter error code 128. When you try to create a new Git repository using the cPanel “cPanel GitTM Version Control” control icon, you get the following error message:

Cmmnd: 
“/usr/local/cpanel/3rdparty/bin/git” reported error code “128” when it ended: Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.

Description 

This occurs when the remote Git repository that you specified in the “Clone URL” field rejects your access. You will learn how to configure key authentication to access the remote repository that you are cloning in this guide.

If you receive the error message described in the symptoms section above, you must use the SSH protocol rather than Git or HTTPS. Git providers usually give you URLs to use for SSH that start with ssh://, or in the case of Github, just a username: git@

Ideally, you will have learned how to add a public SSH key to your remote repository provider’s system so you can access it from your cPanel server by following their instructions, and you will have the SSH version of the Git repository URL for the remote repository that you need to clone before beginning the steps in the guide that is linked below.
