$ jupyter-notebook
[I 18:53:12.601 NotebookApp] Serving notebooks from local directory: /home/j
[I 18:53:12.601 NotebookApp] Jupyter Notebook 6.4.5 is running at:
[I 18:53:12.601 NotebookApp] http://localhost:8888/?token=6df6a314b44a50e058ff27f735d91cbd46bfaf0e403bd2e9
[I 18:53:12.601 NotebookApp]  or http://127.0.0.1:8888/?token=6df6a314b44a50e058ff27f735d91cbd46bfaf0e403bd2e9
[I 18:53:12.601 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 18:53:12.635 NotebookApp] 
    
    To access the notebook, open this file in a browser:
        file:///home/j/.local/share/jupyter/runtime/nbserver-45601-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=6df6a314b44a50e058ff27f735d91cbd46bfaf0e403bd2e9
     or http://127.0.0.1:8888/?token=6df6a314b44a50e058ff27f735d91cbd46bfaf0e403bd2e9


Expected results:
* default web-browser opened and it shows jupyter-notebook interface after redirection from local html-file to http://localhost:8888


Actual results:
* default web-browser opened with error message

> Access to the file was denied
> The file at /home/j/.local/share/jupyter/runtime/nbserver-45601-open.html is not readable.
> It may have been removed, moved, or file permissions may be preventing access.
