Hello James, or anyone else affected,

Accepted dh-python into xenial-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/dh-
python/2.20151103ubuntu1.1 in a few hours, and then in the -proposed

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

  incorrect parsing of != dependency versions

Status in dh-python package in Ubuntu:
  Fix Released
Status in dh-python source package in Xenial:
  Fix Committed
Status in dh-python source package in Yakkety:
  Fix Released

Bug description:
  dh-python incorrectly used != version operators in some cases, resulting in failed package builds; this impacts a number of stable updates for Xenial which blacklist a specific cryptography version.

  [Test Case]
  Build stable release of glance/keystone/nova for xenial/mitaka (parse problem in original bug report)

  [Regression Potential]
  Testing OK in yakkety; change is minimal and ensures != operator is ignored when detected.

  [Original Bug Report]
  Some updates to requirements for openstack projects (glance and keystone specifically) is causing dh-python to incorrectly generate a != version dependency; this is the requires.txt entry:


  which causes (utimately):

  dpkg-gencontrol: warning: can't parse dependency python-cryptography
  (!= 1.3.0)

  from the generated dependency line:

  "python-castellan, python-crypto (>= 2.6), python-cryptography (!=
  1.3.0), python-debtcollector, python-eventlet, python-futurist,
  python-glance-store, python-httplib2, python-iso8601, python-
  jsonschema, python-keystoneauth1, python-keystoneclient, python-
