[Łukasz Zemczak]

Hello Chad, or anyone else affected,

Accepted unattended-upgrades into xenial-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/unattended-upgrades/1.1ubuntu1.18.04.7~16.04.6 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 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.

Bug description:
  [Impact]

   * Changes to the ESM repo naming and the introduction of the new esm-infra and esm-apps suites require an update to unattended-upgrades to ensure the security pockets are used.
   * This change will ensure users are actually receiving updates, where as today they will not without making manual changes.

  [Test Case]

   * 1) Bionic and Xenial ESM-Apps/ESM-infra with Ubuntu Pro
   * 2) Trusty ESM

  [Regression Potential]

   * This change is ensuring users actually receive security updates when using ESM. Therefore, 1) users of ESM-apps on Ubuntu Pro and 2) ESM-infra on Trusty will be the only users affected.
   * The possible issue would be if/when users receive actual security updates that then regress or cause issues to the system.

  [Other Info]
   
  Previous description:

  ESM <distro>-infra-security and <distro>-apps-security will need to
  participate in unattended upgrades.

  Currently /etc/apt/apt.conf.d/50unattended-upgrades provides:
  Unattended-Upgrade::Allowed-Origins {
          "${distro_id}ESM:${distro_codename}";
  }

  Given that there have been ESM apt pocket renames over the last few
  months, the above ESM allowed-origin should not apply anymore and can
  be dropped or replaced.

  See RT #C122697 and #C121067 for the pocket/suite renames related to
  ESM

  What is needed after the ESM apt pocket/suite renames:

  Support for unattended upgrades for ESM for Infrastructure customers:

  Unattended-Upgrade::Allowed-Origins {
    // Extended Security Maintenance; doesn't necessarily exist for
    // every release and this system may not have it installed, but if
    // available, the policy for updates is such that unattended-upgrades
    // should also install from here by default.
    "${distro_id}ESM:${distro_codename}-infra-security";
    "${distro_id}ESMApps:${distro_codename}-apps-security";
  };

  === Confirmed proper origin on an attached Trusty instance with ESM-
  infra enabled:

   500 https://esm.ubuntu.com/ubuntu/ trusty-infra-security/main amd64 Packages
       release v=14.04,o=UbuntuESM,a=trusty-infra-security,n=trusty,l=UbuntuESM,c=main

  === Confirmed proper origins on Bionic for enabled ESM-infra and ESM-apps on an AWS Ubuntu PRO instance:
   500 https://esm.ubuntu.com/infra/ubuntu bionic-infra-security/main amd64 Packages
       release v=18.04,o=UbuntuESM,a=bionic-infra-security,n=bionic,l=UbuntuESM,c=main,b=amd64

   500 https://esm.ubuntu.com/apps/ubuntu bionic-apps-security/main amd64 Packages
       release v=18.04,o=UbuntuESMApps,a=bionic-apps-security,n=bionic,l=UbuntuESMApps,c=main,b=amd64
