[Bug 1562042] Re: Traceback in error log during heat-engine service shutdown

[Martin Pitt]

Hello Ivan, or anyone else affected,

Accepted heat into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/heat/1:6.0.0-0ubuntu1.1 in a few
hours, and then in the -proposed repository.

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
advance!

** Changed in: heat (Ubuntu Xenial)
       Status: In Progress => Fix Committed
