I just recently came across an issue when we were bootstrapping one of our EMR clusters, looks like when trying to import pgpy we failed with the following traceback:

Apparently the cryptography team released a new version on September 7th 2022 that broke the pgpy library.
https://pypi.org/project/cryptography/38.0.1/
We needed to downgrade our version to get things working again. I figured I would post this to see if others run into this, according to the pgpy github page, they are working on a fix.

Here is how I solved it in the meantime, I needed to downgrade the cryptography library.

sudo python3 -m pip install PGPy sudo python3 -m pip uninstall -y cryptography sudo python3 -m pip install cryptography==37.0.4 |
