GitHub OAuth returned 500 Internal Server Error

I set up the Github Oauth using this guide

But after I tried to login with github, Jupyterhub kept showing the following error:

[yuvipanda]

I was able to reproduce this today. It looks like the cause is tornado’s SimpleHTTPClient.

Installing pycurl in the hub environment fixed it. We should ship with that by default.

[carlthewebmaster]

I had this exact issue. It turned out I was upgrading the wrong Tornado. Per this link,

JupyterHub is run from a python3 virtual environment located in /opt/tljh/hub

That was the clue I needed - Once I got into that virutal environment:

$ sudo su -
# cd /opt/tljh/hub
# source ./bin/activate
# pip3 freeze | grep tornado
tornado==6.0.2
# pip3 install tornado==5.1.1
# pip3 freeze | grep tornado
tornado==5.1.1
# exit
$ sudo tljh-config reload proxy
$ sudo tljh-config reload

Worked!
