Comment 10 for bug 1817665

Pre -proposed this just fails right away (as no packages are in trusty at all)

python3 ./create.py
Traceback (most recent call last):
  File "./create.py", line 1, in <module>
    from pymacaroons import Macaroon, Verifier
ImportError: No module named 'pymacaroons'

Using the test I attached to the bug:
python3 ./create.py
location cool-picture-service.example.com
identifier key-for-bob
cid picture_id = bobs_cool_cat.jpg

Sucessfully verified

This uses the full pymacaroons stack and works just fine.
Therefore setting verification done.
