@rafaci. Yeah that is the error that you’ll see when a package is not currently available in pip or conda for that version of python. I believe there is a way to use conda-forge to configure pre-3.8 packages so I’m looking into that now. While the root cause here is the lack of jupyter in that environment I’m keeping this issue open as we didn’t surface a reasonable warning here for you. Which I’d like to fix. If our code doesn’t find Jupyter in the currently selected environment it looks for other environments on disk to use instead, I believe that this probably started up the server from an old environment, and then failed trying to create a 3.8 kernel in it.

Currently anaconda doesn’t support python 3.8 well. Once that issue is addressed we’ll revisit.
