Package: python3-nbconvert Version: 6.1.0-1 Severity: normal Dear Maintainer,
today I wanted to work again with my jupyter notebooks but when I try to open a notebook in the browser, I get a 500 internal server error and the log in the console where I started jupyter-notebook shows the following messages: [guefz@corinnis:~/data/mineral] $ jupyter-notebook --no-browser --notebook-dir python-test/ [I 18:00:53.844 NotebookApp] Serving notebooks from local directory: /home/guefz/data/mineral/python-test [I 18:00:53.844 NotebookApp] Jupyter Notebook 6.4.5 is running at: [I 18:00:53.844 NotebookApp] http://localhost:8888/?token=01856103749006da3a0beaa7d83256462324e12ef589fa11 [I 18:00:53.844 NotebookApp] or http://127.0.0.1:8888/?token=01856103749006da3a0beaa7d83256462324e12ef589fa11 [I 18:00:53.844 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
