Error while creating superuser

[AunErki]

Hi!

I am setting up seqr local docker install.
While trying to set up superuser: "sudo docker compose exec seqr python manage.py createsuperuser"
I get an error:

The most likely cause for this issue is that you are running this command without access to the internet

I indeed had the problems with internet connection. The firewall settings of my virtual machine were off for outgoing traffic.

Thank you for your answer! It helped me to solve this issue.
