apt-get upgrade breaks python3

[edwinbmiller]

reinstalled debian stretch 4.4.77 and did a
apt-get update -y
apt-get install linux-rock64 -y (instead of pt-get upgrade)

then ran the following python

root@rock64:/mnt/home/rock64/0636920028154-master-c581427d3e9fc7ef210dd46d112d2eae4043d557/lp5e-code-1.0-jun1813/code# python3 pybench_cases.py
