I added debug message to assertion to check why User.objects.all() has 2 items instead 1. As you can see, it has two users [<User: hue>, <User: test_remote_user_login>], where the test expects <User: test_remote_user_login> only. Maybe remote login logic has been changed in python3 (or in django 3)?

Steps to reproduce it?

• build hue with python3
• run hue test specific desktop.auth.views_test.TestRemoteUserLogin

Hue version or source? (e.g. open source 4.5, CDH 5.16, CDP 1.0...). System info (e.g. OS, Browser...).
open source latest master branch

'hue' is a system user, there is probably some Py3 in the login view calling the install of it from install_sample_user.
(searching for Installed a user)

This might be a legit thing, we could either dig a bit more or update the test for py3.

useradmin.models: INFO: Installed a user "{'username': 'hue'}"
