Hello!  
I want to run Jupyterhub with the SystemUserSpawner in the Docker container.  
I used the following example for this ([https://github.com/jupyterhub/dockerspawner/tree/main/examples/simple](https://github.com/jupyterhub/dockerspawner/tree/main/examples/simple))  
and only added the following lines to jupyterhub\_config.py:

> from dockerspawner import SystemUserSpawner  
> c.JupyterHub.spawner\_class = SystemUserSpawner

After starting the JupyterHub container, I created a user “abc” inside the JupyterHub container:

> useradd -m abc

After that I logged into the JupyterHub with “abc” and wanted to start a notebook. Here came the following error message:

Can anyone tell me what I am doing wrong?
