Comment 21 for bug 1833229

Right - I was able to reproduce this issue on focal using:

python3 -m venv /tmp/test3env
source /tmp/test3env/bin/activate
pip install wheel
pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple pytopo==1.6.1

(thanks for that)

However with the patched package in the PPA, I now hit a completely different problem with the test case which looks related to the patch:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:
