[Norbert Preining]

Hi Ximin,

> $ for file in /etc/jupyter/nbconfig/*.json; do if [ -f "$file" ] && [ -r "$file" ]; then echo "-- $file"; cat "$file"; echo; fi; done

-- /etc/jupyter/nbconfig/common.json

-- /etc/jupyter/nbconfig/edit.json

-- /etc/jupyter/nbconfig/notebook.json

-- /etc/jupyter/nbconfig/terminal.json

-- /etc/jupyter/nbconfig/tree.json

All are empty

done, no file left.

> $ dpkg-reconfigure jupyter-nbextension-jupyter-js-widgets

That didn't work (/usr/sbin/dpkg-reconfigure: jupyter-nbextension-jupyter-js-widgets is broken or not fully installed)

But
	dpkg --configure -a
succeeded:

$ dpkg --configure -a
Setting up jupyter-nbextension-jupyter-js-widgets (6.0.0-2) ...
/usr/lib/python3.5/runpy.py:125: RuntimeWarning: 'notebook.nbextensions' found in sys.modules after import of package 'notebook', but prior to execution of 'notebook.nbextensions'; this may result in unpredictable behaviour

Yes, configure succeeded.

No idea how these files were created, though!

All the best and thanks a lot
