I’m on the git challenge now in the part of Branches Aren’t Just For Birds i added the file and i can’t push to the repository the error is :

remote: Permission to jlord/patchwork.git denied to adibcod.
fatal: unable to access ‘https://github.com/jlord/patchwork.git/’: The requested
URL returned error: 403

From memory, I think you’re supposed to push to your forked version of the repo. You can’t push to the original, as you don’t have permission.
