PermissionError: [Errno 13] Permission denied when accessing to aws ec2

Question

I have ubuntu 16.04 running on virtual box(on mac), and on aws ec2 ubuntu 18.04 running. I am trying to run Jupiter notebook on aws.ec2 and trying to access it remotely thru my web browser on my local Ubuntu. I am able to access remote ubuntu(aws.ec2) terminal. After I followed the steps on this link

I got the following error on the step 9.

I reinstalled everything from scratch 3 times(including local ubuntu and aws ec2 instance), but no progress so far.

Note1: on ec2 instance, Ubuntu has 18.04 version and it came with python 3.6.3 then I have to install anaconda on the top of it and then the python version now is 3.5.2 once I typed $python3.

Note2: Despite after the anaconda has been installed into the EC2 then the python version degraded to 3.5.2

once I have checked the following directory /usr/local/lib/ there only python3.6 folder is existing, then I typed $sudo chmod 777 dist-packages/

then $jupyter notebook, then copy the token link and combine with dns, but still didn't worked.

I had the same problem, and now I just solved it by trying a couple things. Try these solutions to see if it helps:

1. Changed the ownership of the /home folder and ~/.local/share/jupyter/ folder to current user running this command:

   sudo chown -R $USER /home/

   sudo chown -R $USER ~/.local/share/jupyter/

2. If you encounter ssl error problem, check out this link.

3. Make sure you type https://<jupyter-server-ip> in your browser instead of http://.

4. If you have Your connection is not private problem in your chrome and can not proceed, try safari or other browsers. This happens in chrome with version 70 or newer.
5. Try Leon Huang's solution to turn on the port 8888 for your instance.
