Jupyter notebook permission denied, unable to save

Question

I am having permission denied for Jupyter notebook running on Ubuntu, AWS E2 instance. Below is the image for the error

I have tried to use other browser, reinstall it and clear cache. None of it works.

Answer 1

If your notebook is configured with some auth code (generated by notebook by default), and you've cleared your cache, and cookies, you will get the screen similar to below:

Here you can use the token shown in terminal, while running the notebook, the log will be similar to the below:

    To access the notebook, open this file in a browser:
        file:///home/ubuntu/.local/share/jupyter/runtime/nbserver-19740-open.html
    Or copy and paste one of these URLs:
        http://ip-123-1-1-123:8888/?token=abcdefghijl
     or http://127.0.0.1:8888/?token=abcdefghijl

and if you want to run notebook without authentication you can run the below command:

jupyter notebook --ip='0.0.0.0' --NotebookApp.token='' --NotebookApp.password=''

Also try creating a new notebook, instead of accessing the Test.ipynb again, so that you can figure out if the issue is from the specific file or whole server.

Answer 2

The main reason is i don't have the permission to overwrite the file. First of all, i create the file at /home/ubuntu, which I don't have permission of. So i create a folder to store the file inside it. Other than that, i also done quite a lot modifications including adding the inbound rules and the permissions, i think some of it did help. I list out some of the website i think is very useful in tackling this issue:

1. PermissionError: [Errno 13] Permission denied: Cannot open Jupyter on Browser despite running correctly on AWS EC2 instance
