User Servers Fail to boot after system reboot

[ynnelson]

So JupyterHub was working just fine but after messing with the Kernel list and creating some new environments it no longer works after we rebooted the system.

I keep getting stuck on this screen:

Looking at the journalctl of the user's server this is what I get below. It looks like it's looking for the jupyterhub module and can't find it. I did source /opt/tljh/user/bin/activate and checked that the jupyterhub module exists and it does... My guess is somehow the user server are no longer being launched using the virtual env that tljh setup but I have no idea how to remedy that...

Any help would be super helpful!!

It seems your user environment no longer contains the jupyterhub package, which is required to start the user servers.
