Just updated Ubuntu to 22.04, now I can't open Jupyter Notebook-CodePudding

When I try to launch Jupyter Notebook, the browser launches and I get the following error:

Access to the file was denied

The file at /home/benjamin/.local/share/jupyter/runtime/nbserver-11758-open.html is not readable.

It may have been removed, moved, or file permissions may be preventing access.

I tried running

jupyter lab clean --all
pip3 install jupyterlab --force-reinstall

as per the suggestion from here: Jupyter Notebook: Access to the file was denied. The commands ran, but I still get the Access to the file was denied error. Also, on the reinstall command it spits this out:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.2.5 requires pyqt5<5.13, which is not installed.
spyder 4.2.5 requires pyqtwebengine<5.13, which is not installed.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.
anaconda-project 0.9.1 requires ruamel-yaml, which is not installed.
spyder 4.2.5 requires jedi==0.17.2, but you have jedi 0.18.1 which is incompatible.
spyder 4.2.5 requires parso==0.7.0, but you have parso 0.8.3 which is incompatible.
sphinx 4.0.1 requires Jinja2<3.0,>=2.3, but you have jinja2 3.1.1 which is incompatible.
sphinx 4.0.1 requires MarkupSafe<2.0, but you have markupsafe 2.1.1 which is incompatible.
python-language-server 0.36.2 requires jedi<0.18.0,>=0.17.2, but you have jedi 0.18.1 which is incompatible.
fermipy 1.0.1 5.g5a57 requires astropy<4, but you have astropy 4.2.1 which is incompatible.

which may or may not be part of the problem.

CodePudding user response：

did you try setting

c.NotebookApp.use_redirect_file = False

In the jupyter_notebook_configuration.py file?

If you tried, did you remove the '#' at the start of the line?

I had the same problem with Ubuntu 22.04 and this fixed it.

CodePudding user response：

I have the same exact problem after switching to 22.04 today. Are you using Firefox? I normally use chromium but it doesnt work with jupyter so I use firefox, but I also tried with chromium and its the same error. I tried that solution that keeps coming up (variable = False) and I tried playing with the permissions to no avail.
