[Bug 1524989] Please test proposed package

[Ryan Beisner]

Hello Xing, or anyone else affected,

Accepted python-os-brick 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!
