I'm unable to reproduce this on Ubuntu 22.04 when I downloaded the latest install script. Can you try installing the latest version of this sdk with the following steps:

git clone https://github.com/aws/aws-iot-device-sdk-python-v2.git
python3 -m pip install ./aws-iot-device-sdk-python-v2
python3 aws-iot-device-sdk-python-v2/samples/pubsub.py --endpoint a3dkrncnrub5qb-ats.iot.us-east-2.amazonaws.com --ca_file root-CA.crt --cert lab_nuc_test.cert.pem --key lab_nuc_test.private.key --client_id basicPubSub --topic sdk/test/python --count 0

seemed to have solved this by deleting the downloads directory and following the tutorial again in a new one
