Cannot open new Jupyter Notebook [Permission Denied]

Question

I have installed Jupyter Notebook on ubuntu 16.04 using pip3. I can execute jupyter notebook command. It opens and shows a list of current path directories.

Answer 1

change the ownership of the ~/.local/share/jupyter directory from root to user.

sudo chown -R user:user ~/.local/share/jupyter 

see here: https://github.com/ipython/ipython/issues/8997

The first user before the colon is your username, the second user after the colon is your group. If you get chown: [user]: illegal group name, find your group with groups, or specify no group with sudo chown user: ~/.local/share/jupyter.

EDIT: Added -R option in comments to the answer. You have to change ownership of all files inside this directory (or inside ~/.jupyter/, wherever it gives you PermissionError) to your user to make it work.

Answer 2

This worked for me:

-> uninstalled Jupyter
-> install jupyter in Python36 folder
-> open Jupyter from command prompt instead of git bash.

Answer 3

Tried everything that was suggested but finally this helped me:

sudo jupyter notebook --allow-root

In my case, it didn't start the browser by itself. So just copy the link from terminal and open it by yourself.

Update: Change folder(.local) permissions by this command:

sudo chmod -R 777 .local

Answer 4

I had to run chown recursively for all subfolders With /* . Than it worked:

sudo chown -R user:usergroup /home/user/.local/share/jupyter/*

Answer 5

You don't have to install or uninstall anything. if you are using python 2 use pip to install and upgrade. But if you want to use python3 then follow the steps below:

sudo apt-get install python3-pip python3-dev

then in terminal use this

pip3 install -U jupyter

final step is to launch jupyter notebook so,in terminal just type

jupyter notebook

all the issues or problems of premissions etc will be resolved.

this problem of not able to open jupyter notebook is like Corona virus.I came across several complaints-including my own.I use windows 10.

Atlast after struggling for 3 days i came across this wonderful foolproof solution:-

1.The jupyter folder is created at path:- C:\Users\deviv_000\AppData\Roaming\jupyter your name will replace->deviv_000

2.Go to cmd and write : cd C:\Users\deviv_000\AppData\Roaming\jupyter this will take cmd to that folder.

3.Now create manually a file as untitled.ipynb in jupyter folder.

4.Come back to cmd and write: jupyter trust untitled.ipynb

5.After cmd performs this operation now write:-
jupyter notebook

SUCCESS!!- your notebook will appear in the next tab.I used chrome.
