[SRU] Please backport UbuntuDistroInfo().get_all(result="object") to Xenial

Debdiff of xenial attached.

This needs special handling / consideration from the Canonical teams and the Release team before this can be added.

Xenial has already left End of Standard Support, so the Release and Canonical teams need to decide if they want to out-of-band update/patch this.

We have an exception for ubuntu-advantage-tools because it provides the "gateway" to Pro for users - without that we'd end up with a circular problem that would just make it difficult for users to initially enable Pro.

I think probably that also should apply to other packages involved in providing that gateway. It sounds like this should qualify. I'll ask to see if there's SRU team consensus on this.

SRU team opinion seems to be that on the question of updating xenial-updates after EOSS, this is fine in principle in this case for the reason above. Note that this is subject to review of the actual upload - it should be trivial and straightforward; I haven't reviewed the debdiff itself.

While testing this update as a part of the sponsorship process I noticed that the eol-esm date for Ubuntu 16.04 is incorrect in the version of ubuntu.csv included with distro-info-data for Ubuntu 16.04 so that will likely need an update too.

I've gone ahead and sponsored this debdiff for Xenial. Thanks!

Oh, right. Thanks Brian. dput-ng refused to upload to xenial and I failed fighting against it.

Accepting into xenial-proposed. However, before marking verification-done-xenial, please also get your software-properties update into xenial-proposed and also verified, so that we are testing and landing everything together, so that we do not end up iterating in xenial-updates if something here needs tweaking and it's only detected when trying to land the full user story.

(if necessary that would mean a versioned Depends from the updated software-properties to the new distro-info in xenial-updates, which would seem appropriate).

Hello Nathan, or anyone else affected,

Accepted distro-info into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/distro-info/0.14ubuntu0.3 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 on 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, what testing has been performed on the package and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

All autopkgtests for the newly accepted distro-info (0.14ubuntu0.3) for xenial have finished running.
The following regressions have been reported in tests triggered by the package:

juju-core/unknown (armhf)
update-notifier/unknown (armhf)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!
