Jupyter: An error occurred while creating a new notebook

I have ununtu 18.04.1 installed as well as the anaconda 4.5.8.

After typing:

$ jupyter notebook

I get the standard jupyter homepage.

But when I try to click New/Notebook/Python3 I get the following error:

Creating Notebook Failed>An error occurred while creating a new notebook>Permission denied: Untitled.ipynb

How can I fix this?

When I type anaconda navigator into terminal the GUI below starts. I can then start s jypter notebook that works by simply clicking on the jupyter notebook tab.

However I can't see the anaconda prompt anywhere neither the GUI above on in the original terminal session?

desktop:~$ cd /Projects/jupyter-notebook
desktop:/Projects/jupyter-notebook$ anaconda-navigator

It's not possible to type anything in this terminal session while anaconda navigator is still running!

Solution 1:

1. Open the terminal and start Anaconda Navigator with the following command:

   anaconda-navigator  
   

2. In Ananconda Navigator select Environments (in left pane) -> Python35 -> Open Terminal.

3. Click Open Terminal and run the following command to start Jupyter Notebook:

   jupyter-notebook  
   

   This command starts the Jupyter that is installed in Anaconda, so the Python 3 that is installed in Anaconda is able to recognize it.

Solution 2:

I also faced this problem and solved it very simply following these steps:

1. Close all Jupyter Notebook tabs on the web browser.
2. Terminate all Jupyter processes in the terminal.
3. Open a new Jupyter Notebook.
