I had this issue as of 22/03/2019, and what worked for me was updating conda and then upgrading jupyter using pip:

conda update --all
pip install jupyter --upgrade

Answer 5

Use this ::

python2 -m pip install ipykernel

python3 -m pip install ipykernel
python3 -m ipykernel install --user

I had the same problem and my solution was update the Jinja2 package to version Jinja2-2.8.

To update it I used the easy_install command as follow:

sudo easy_install -U python-jinja2[all]

After that the 500 : Internal Server Error was fixed.
