Problem upgrading to Jupyterlab 1.0.2

[carluri]

Hello,

I'm trying to upgrade the jupyterlab version to the new stable version 1.0.2. To do this, I execute the command

conda install -c conda-forge jupyterlab

in the base conda environment that is installed by default via the ansible script.

In this process, python gets upgraded to version 3.7. However, after everything is finished the jupyterhub gives me a 502 Bad Gateway and I haven't been able to fix it.

What is the correct way to upgrade the hub to python 3.7 and be able to use the latest version of jupyterlab?

thanks in advance for any help.
