Just adding context; this issue broke both branches;
related commit to 2.0 branch is: 9b5fcc2

I thought this package was in the base images we use? see

I know! A new version was released May 06, which is the day our builds broke:

Further investigation may be required to truly understand how this broke our builds.

I can confirm this issue has nothing to do with the upstream Docker images as I am able to build:

• https://github.com/jupyter/docker-stacks/blob/main/images/base-notebook/Dockerfile#L42

I am also able to build the refactored JupyterLab image:

• https://github.com/StatCan/aaw-kubeflow-containers/blob/images-refactoring/dockerfiles/jupyterlab/Dockerfile

This is for main and no longer an issue.
