Comment 11 for bug 1738412

The DEP8 tests in http://people.canonical.com/~ubuntu-archive/proposed-migration/xenial/update_excuses.html are failing for squid3 but for a different reason. Before (http://autopkgtest.ubuntu.com/packages/squid3/xenial/amd64) they wouldn't even start.

For example, see https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-xenial/xenial/amd64/s/squid3/20181029_225503_190aa@/log.gz which ends with:

badpkg: Test dependencies are unsatisfiable. A common reason is that your testbed is out of date with respect to the archive, and you need to use a current testbed or run apt-get update or use -U.

That and a few other things is what was fixed. The tests now run locally at least, with autopkgtest. The current failure in the autopkgtest infrastructure from Ubuntu is firewall related, as some tests try to reach out to public facing websites like www.ubuntu.com:

I don't think the above is worth fixing at the moment, because:
a) it's a long process: reject package from proposed, prepare new one, upload, get sru team to approve, then let it lose in the autopkgtest infrastructure to see if it works
b) bileto isn't working for this for some reason, I can't get test results from it. It just says "test running (always failed)", and no logs.
c) package that is currently in proposed is already an improvement, as the test now can be run locally (and pass).
