Error installing jupyterhub (TLJH): AssertionError

JupyterHub The Littlest JupyterHub

Hello

I followed the instructions on: Install the littlest jupyter hub on your own server, but during the installation process in step 1.3, using the command curl -L https://tljh.jupyter.org/bootstrap.py | sudo -E python3 - --admin <admin-user-name>, I encountered the following error:

Downloaded conda installer https://github.com/conda-forge/miniforge/releases/download/23.1.0-1/Mambaforge-23.1.0-1-Linux-x86_64.sh in 10.3s

Was this a fresh installation on a VM, or did you have something since before?
