[Bug 1594776] Re: add-apt-repository explodes on missing ppa

[Brian Murray]

Hello Mark, or anyone else affected,

Accepted software-properties into xenial-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/software-properties/0.96.20.3 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: software-properties (Ubuntu Xenial)
       Status: Triaged => Fix Committed

** Tags added: verification-needed
