Incompatible with `jupyter-labhub`

See original GitHub issue

Bug description

As soon as I try to use a nbgitpuller Link with the jupyter-labhub Backend I only get a “Internal Server Error” and some errors in the logs. Using the “normal” backend works fine.

Expected behaviour

Normal cloning of the repo.

Actual behaviour

HTTP Status 500

How to reproduce

Start single user nb with jupyter-labhub and try to open a nbgitpuller link

@fritterhoff thanks for digging into the problem, and providing a minimal example! It looks like there’s a mix of notebook and jupyter-server, I think this should fix it:

So I’m able to provide some instructions to reproduce the bug:

  1. Build a docker image using the following content as Dockerfile
FROM jupyter/scipy-notebook:2021-12-16
USER root

RUN pip install --no-cache-dir nbgitpuller && \
    fix-permissions "${CONDA_DIR}" && \
    fix-permissions "/home/${NB_USER}" 


or even more simple:

FROM jupyter/scipy-notebook:2021-12-16

RUN pip install --no-cache-dir nbgitpuller
  1. Run the docker image using docker run --rm -it -p 8888:8888 test jupyter lab (replace the image name with your own)
  2. Try to open the jupyterlab using the printed link and afterwards try to pull a git repo (e.g.
  3. You should now see the error message in terminal where you started the jupyter lab
