I managed to start my jupyterhub server through docker container. I enabled the GitHub OAuth also. I am able to go to public folders created in my organization, but unable to connect to internal folders created.
It threw “returned non-zero exit status 128.” and said “fatal: could not read Username for ‘https://github.com’: No such device or address”.
But I wonder why it is working for public repositories and throwing error only for internal repositories.
