Как выполнить jupyterhub на сервере человечности (AWS)

Я пытаюсь выполнить jupyterhub со много пользователями от AWS, но я получаю ошибку.

Я использую команду ubuntu@ip-172-31-23-74:~$ sudo /home/ubuntu/.local/bin/jupyterhub

и это - ошибка, которую я получаю, когда я пытаюсь зарегистрироваться с одним из пользователей.
