autopkgtest fail

I suspect the test might require internet access, but it's not clear why it worked before, since the last pass was the same exact package:

E vcr.errors.CannotOverwriteExistingCassetteException: No match for the request (<Request (POST) https://squid.internal:3128/00000000-0000-0000-0000-000000000000/services/webspaces//eastuswebspace/sites>) was found. Can't overwrite existing cassette ('/tmp/autopkgtest.STWYRh/autopkgtest_tmp/tests/recordings/test_legacy_mgmt_website.test_get_web_site.yaml') in your current record mode ('none').

Locally in lxd, and also on diglett, the dep8 tests passed, using eoan-proposed.

Adding a task for python-cryptography so this bug shows up in the excuses page, even though it's not a bug in python-cryptography itself.

Given the tests pass locally in a container (autopkgtest ... -- lxd ubuntu-daily;eoan), I'm trying a bileto run (https://bileto.ubuntu.com/#/ticket/3818) to see if that reproduces the test failure. If yes, then I can use that platform for troubleshooting.

the latest autopkgtest retries show that the problem is present in the release pocket, so I have hinted away the failure and am closing the tasks on the reverse-dependencies, since they will no longer be blocked.

The python-azure test failed in bileto in the same way, so it can be used to further troubleshoot this issue. My first attempt would be to unset the http_proxy variable, or set it to localhost so connections fail, and see what happens.

I ran autopkgtest using squid.internal and the test failed with these errors:

The test_receipt_url_bad_endpoint attempts to contact "http://notreal.azure.com" and then compares the returned information to an "Invoice_1.pdf" included in the source package.

The following change will skip the tests that will not pass in Ubuntu's autopkgtest infrastructure:
