Enable sharing jupyter server: scope 'shares!user' for role user does not exist

JupyterHub

1

Hi,
I am trying to give users the ability to share their servers with other users.
They are managed via LDAP.
Following the documentation at Sharing access to user servers — JupyterHub documentation

I set the following in jupyterhub_config.py:

c.JupyterHub.load_roles = [
    {
        "name": "user",
        "scopes": ["self", "shares!user"],
    },
]

However, when I deploy the stack on my swarm I get:

# docker stack deploy -c docker-compose.yaml jupyter
Creating service jupyter_jupyterhub
# docker service logs -f jupyter_jupyterhub

sharing permissions requires JupyterHub 5, which is not yet released. Are you running from HEAD?

Thanks for your answer, yes I saw that info 2 days ago. I use the docker image and the latest is 4.0.2 so I guess I will have to wait …
