Hello,
I installed TLJH on Ubuntu Server 22.04 (This should work: [removed bc I can only include 2 links] github[dot]com/jupyterhub/the-littlest-jupyterhub/issues/813) on a local machine - following these instructions:
except I didn’t use Ubuntu 18.04.
This version said to use 18.04 or 20.04: [removed bc I can only include 2 links] The Littlest JupyterHub — The Littlest JupyterHub documentation
And afaik the installation finished.
(Firewall config should be fine, as it is turned off for now. Also on my first try I also installed nextcloud and got to the loginscreen of nextcloud.)
I found this older entry on github: github[dot]com/jupyterhub/the-littlest-jupyterhub/issues/438

Any chance someone could give me some advice?
