KeyboardInterrupt thrown on papermill notebook execution when executing on RHEL 8 versus RHEL7?

[metaperl]

Hello, we have a Jupyter notebook that runs just fine under papermill on RHEL 7. However in RHEL 8, the notebook does not execute any cells before throwing a KeyboardInterrupt error.

As you know a KeyboardInterrupt exception implies human interruption of a process. But in this case, there is not human interruption.

I would provide a stack trace but company confidentiality agreements prohibit that.

We are using papermill 2.4.0 on Python 3.9.
