Ok finally I got the notebook upload button working, but in the system python installation (using sudo). The Anaconda installation in the user space is giving the error above.

This command is missing in your tutorial, but jupyter requires this for extension to work.

[sudo] jupyter nbextension enable --py --sys-prefix widgetsnbextension

Should we refer to Notebook extensions, as in some cases the --user flag or sudo right are required?

@peteut that article in link is pretty lengthy, what do you mean in the essence with your last sentence?
