Comment 1 for bug 1652329

I've struggled a bit to get all this sorted out in ubuntu-image, but I have a workable solution, at least for X, Y, and Z. I only use flake8, with `sitepackages=True` and a few little tricks and plugins to get it all passing. One other thing I did with pitti before he left was to hook up GH CI to autopkgtest, so the tests are all running on the ubuntu ci machinery, exactly as it would for -proposed promotion. That includes package build times and DEP-8 tests.

Check out ubuntu-image on GH and happy to chat about it more after the holidays. I think it would make a lot of sense, if possible, for these three projects to have some consistent CI set up (although our coding styles may be minorly different).
