Jupyter Notebook does not load using ubuntu 18.04 LTS in windows 10

[mckot]

The local host does not open on any browser.
The following error is shown.

jupyter-notebook also doesn't work.

I had the same problem as you. This is not my solution I find it here. Thanks to Atto Yusuke_konishi.

He has two methods to fix it and and I used method 1 and it worked:
$ jupyter notebook --NotebookApp.use_redirect_file=False

for jupyter lab:
$ jupyter lab --NotebookApp.use_redirect_file=False

to make it easy to use every time:

$ echo "alias jn='jupyter notebook --NotebookApp.use_redirect_file=False'" >> ~/.bashrc
$ source ~/.bashrc
$ jn

for jupyter lab"

$ echo "alias jb='jupyter lab --NotebookApp.use_redirect_file=False'" >> ~/.bashrc
$ source ~/.bashrc
$ jb

$ echo "alias jb='jupyter lab --NotebookApp.use_redirect_file=False'" >> ~/.bashrc
$ source ~/.bashrc
$ jb

It is easier to place this setting in the jupyter_config.py file. In that way, you do not have to have an alias or editing of .bashrc

# Generate jupyter_config.py if it does not exists
jupyter jupyter notebook --generate-config

# Use nano or whatever editor. I use vs code
code ${USER}/.jupyter/jupyter_notebook_config.py

# Search and uncomment `c.NotebookApp.use_redirect_file=True` and set it to False
c.NotebookApp.use_redirect_file=False

In WSL 2, I had to add more to get the correct IP address.

# c.NotebookApp.ip = 'localhost'
import subprocess

c.NotebookApp.ip = subprocess.run(
    ["hostname", "-I"], capture_output=True, text=True
).stdout.strip()

I think you'd only run into this if you tried to set your BROWSER environment variable, because without it, you would either get a yellow warning message telling you "No web browser found: could not locate runnable browser." or a WSL installed webbrowser would be launched (for example, I have w3m and jupyter notebook by default will launch that in WSL.

You can find more about how to work around this issue to use the Windows browser over here: http://github.com/jupyter/notebook/issues/4594

I'm going to go ahead and close this one, as it is not a jupyter_core issue - the launched of the browser is done via the python webbrowser module in the jupyter-notebook subproject.

Happy hacking!

This need not be a Windows-only problem. Basically, the browser might not have access to user's dotfiles (e.g. Firefox installed via snap). And then the only way around seems to be pass, in some way, e.g. as above, or in jupyter_notebook_config.py the parameter NotebookApp.use_redirect_file=False to jupyter.

Perhaps this issue should be better documented - e.g. we just spent time figuring this out: https://groups.google.com/g/sage-support/c/22Uj6xrP8zo/m/7M4OYU3qDgAJ

@ivanov Another scenario where one sees this is when jupyter is launched in crostini (a Chromeos VM); then in crostini terminal (Debian guest OS) one sees

$ jupyter-notebook Untitled.ipynb 
[I 17:18:04.802 NotebookApp] Serving notebooks from local directory: /home/dimpase/foo/bar
[I 17:18:04.802 NotebookApp] Jupyter Notebook 6.2.0 is running at:

    To access the notebook, open this file in a browser:
        file:///home/dimpase/.local/share/jupyter/runtime/nbserver-8789-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=a1afee7184e620439aafad309355c9d467ca1cf7a8642964

but in the browser (Chrome running on the ChromeOS host) one sees ERR_FILE_NOT_FOUND, upon trying to open
file:///tmp/tmpounu3jr9.html (as the host OS has no access to guest's /tmp/)

Whereas

jupyter-notebook --NotebookApp.use_redirect_file=False Untitled.ipynb 

works just fine.
