Hi Rogério, Did you previously have jupyter-notebook version 4.2.3-2 installed? If so, then this is the same as:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847917 and all you need to do is remove any empty *.json files in /etc/jupyter/nbconfig. Please also let me know, so that I can close this bug. If it is not the same as the above linked issue, please send me the output of `ls -la /etc/jupyter/nbconfig` (and ideally the full contents) so that I can try to debug the problem.
