Bug description

On first install of tljh on Ubuntu 22.04.3 LTS, the page "Your server is starting up" after logging in fails with "Spawn failed: Server at http://127.0.0.1:45679/user/marc/ didn't respond in 30 seconds".

Looking at the logs with sudo journalctl -u jupyter-<name-of-user> I see the trace

Feb 22 11:22:39 grove systemd[1]: Started /opt/tljh/user/bin/jupyterhub-singleuser.
