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

Based on my experience on Ubuntu 18.04:

1. Check Jupyter installation

first of all make sure that you have installed and/or upgraded Jupyter-notebook (also for virtual-environment):

pip install --upgrade jupyter 

2. Change the Access Permissions (Use with Caution!)

then try to change the access permission for you

sudo chmod -R 777 ~/.local

where 777 is a three-digit representation of the access permission. In sense that each of the digits representing short format of the binary one (e.g. 7 for 111). So, 777 means that we set permission access to read, write and execute to 1 for all users (Owner, Group or Other)

Example.1

777 : 111 111 111

or

777 : rwx-rwx-rwx

Example.2

755 : 111 101 101

• Owner: rwx=4+2+1=7
• Group: r-x=4+0+1=5
• Other: r-x=4+0+1=5

(More about chmod : File Permissions and attributes)

3. Run jupyter

afterwards run your jupyter notebook:

jupyter-notebook

Note: (These steps also solve your Visual-Studio code (VS-Code) problems regarding permissions while using ipython and jupyter for python-interactive-console.)
