[Bug 1601986] Please test proposed package

Tue Jan 3 18:27:17 UTC 2017

Hello Peter, or anyone else affected,

Accepted python-cryptography into liberty-proposed. The package will
build now and be available in the Ubuntu Cloud Archive in a few hours,
and then in the -proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:liberty-proposed
  sudo apt-get update

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-liberty-needed to verification-liberty-done. If it
does not fix the bug for you, please add a comment stating that, and
change the tag to verification-liberty-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
advance!

** Changed in: cloud-archive/liberty
       Status: Triaged => Fix Committed

Title:
  RuntimeError: osrandom engine already registered

Status in Ubuntu Cloud Archive:
  Fix Released
Status in Ubuntu Cloud Archive liberty series:
  Fix Committed
Status in OpenStack Dashboard (Horizon):
  New
Status in python-cryptography package in Ubuntu:
  Fix Released

Bug description:
  Horizon errors with 500 Internal Server Error.

  The apache error.log logs an exception "RuntimeError: osrandom engine
  already registered", cf. traceback below. We need to restart apache2
  to recover.

  This happens in a non-deterministic way, ie. Horizon will function
  correctly for some time after throwing this error.

  Versions:

  python-django-horizon            2:8.0.1-0ubuntu1~cloud0 
  apache2                          2.4.7-1ubuntu4.10     
  libapache2-mod-wsgi              3.4-4ubuntu2.1.14.04.2
