Bug description:
  [ Impact ]

   * unattended-upgrades are enabled by default in Ubuntu 16.04 and
  later

   * Currently the following three things happen as a monolithic event:
     - metadata updates: apt update
     - download of updates: apt upgrade --download-only
     - application of updates: apt upgrade

   * For the long running instances, all of the above happens at random
     times throughout the day.

   * If systems were poweredoff / suspended, this happens on boot /
  resume

   * End-users would like to have predictable timing, and control over when
     the updates happen.

  Considering all of the above, the following new behavior is proposed
  which should address all concerns in question. It combines all the
  desired properties from both end-user and mirror perspectives.

  [ Proposed Default Behavior ]

   * Decouple unattended-upgrades application, from apt update

   * apt update:
     - shall be a systemd timer based unit, triggered every 12h with a
   random delay of 12h, therefore executed randomly twice a day.
     - if unattened-upgrades (default on), or download-upgreadaeble-packages
   are enabled, it should result in updates being downloaded aka
   `apt upgrade --download-only`

   * unattended-upgrades:
     - shall be a separate systemd timer based unit triggered at 6am local
   time with a random delay of 1h, therefore executed between 6am and
   7am local time.

   * On boot / resume:
     - if we have missed one, or more, apt update timers,
   apt update / download upgrades / unattended-upgrade will happen in
   sequence. This may result in mirror spikes, but we do want to secure
   cold/stale-booted systems as soon as possible.

  [Test Case]

   * Run system for more than 24h, and check that apt updates were
     automatically executed twice.

   * Check that unattended upgrades were triggered to be applied at
     6am..7am window, if any.

   * Poweroff the machine over the period when apt-get update was
     scheduled, poweron and observe that apt-get update / download /
     unattended upgrade are all performed on boot.

   * Downgrade systemd to the release version of the package (from
     -security). Remove apt periodic stamp files rm /var/lib/apt/periodic/*.
 Then run 'sudo systemctl start apt-daily.service'.
     Confirm that the systemd package is downloaded, but not upgraded.

  [Regression Potential]

   * The newly proposed behavior is a mix of Pre-xenial behavior of "do
     everything at 6am..6:30am window" and the xenial+ behavior of "do
     everything at random times throughout the day". If there are specific
     deployments that rely on the previous types of behaviour they will be
     able to adjust manually the systemd timers with the overrides to be
     executed exactly as they wish; or match the .0 release behaviour that
     they prefer.

   * If timers behavior is coded wrongly the proposed behaviour might not be
     executed as intended, thus requiring further SRUs to bring us in-line
     with the great expectations.

[Brian Murray]

Hello Dimitri, 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/1.1ubuntu1.18.04.7~16.04.0 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.

   * For the long running instances, all of the above happens at random
     times throughout the day.

   * If systems were poweredoff / suspended, this happens on boot /
  resume

   * End-users would like to have predictable timing, and control over when
     the updates happen.

  Considering all of the above, the following new behavior is proposed
  which should address all concerns in question. It combines all the
  desired properties from both end-user and mirror perspectives.

  [ Proposed Default Behavior ]

   * Decouple unattended-upgrades application, from apt update

   * apt update:
     - shall be a systemd timer based unit, triggered every 12h with a
   random delay of 12h, therefore executed randomly twice a day.
     - if unattened-upgrades (default on), or download-upgreadaeble-packages
   are enabled, it should result in updates being downloaded aka
   `apt upgrade --download-only`

   * unattended-upgrades:
     - shall be a separate systemd timer based unit triggered at 6am local
   time with a random delay of 1h, therefore executed between 6am and
   7am local time.

   * On boot / resume:
     - if we have missed one, or more, apt update timers,
   apt update / download upgrades / unattended-upgrade will happen in
   sequence. This may result in mirror spikes, but we do want to secure
   cold/stale-booted systems as soon as possible.

  [Test Case]

   * Run system for more than 24h, and check that apt updates were
     automatically executed twice.

   * Check that unattended upgrades were triggered to be applied at
     6am..7am window, if any.

   * Poweroff the machine over the period when apt-get update was
     scheduled, poweron and observe that apt-get update / download /
     unattended upgrade are all performed on boot.

   * Downgrade systemd to the release version of the package (from
     -security). Remove apt periodic stamp files rm /var/lib/apt/periodic/*.
 Then run 'sudo systemctl start apt-daily.service'.
     Confirm that the systemd package is downloaded, but not upgraded.

  [Regression Potential]

   * The newly proposed behavior is a mix of Pre-xenial behavior of "do
     everything at 6am..6:30am window" and the xenial+ behavior of "do
     everything at random times throughout the day". If there are specific
     deployments that rely on the previous types of behaviour they will be
     able to adjust manually the systemd timers with the overrides to be
     executed exactly as they wish; or match the .0 release behaviour that
     they prefer.

   * If timers behavior is coded wrongly the proposed behaviour might not be
     executed as intended, thus requiring further SRUs to bring us in-line
     with the great expectations.

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, details of your
testing will help us make a better decision.

Bug description:
  [ Impact ]

   * unattended-upgrades are enabled by default in Ubuntu 16.04 and
  later

   * Currently the following three things happen as a monolithic event:
     - metadata updates: apt update
     - download of updates: apt upgrade --download-only
     - application of updates: apt upgrade

   * For the long running instances, all of the above happens at random
     times throughout the day.

   * If systems were poweredoff / suspended, this happens on boot /
  resume

   * End-users would like to have predictable timing, and control over when
     the updates happen.

  Considering all of the above, the following new behavior is proposed
  which should address all concerns in question. It combines all the
  desired properties from both end-user and mirror perspectives.

  [ Proposed Default Behavior ]

   * Decouple unattended-upgrades application, from apt update

   * apt update:
     - shall be a systemd timer based unit, triggered every 12h with a
   random delay of 12h, therefore executed randomly twice a day.
     - if unattened-upgrades (default on), or download-upgreadaeble-packages
   are enabled, it should result in updates being downloaded aka
   `apt upgrade --download-only`

   * unattended-upgrades:
     - shall be a separate systemd timer based unit triggered at 6am local
   time with a random delay of 1h, therefore executed between 6am and
   7am local time.

   * On boot / resume:
     - if we have missed one, or more, apt update timers,
   apt update / download upgrades / unattended-upgrade will happen in
   sequence. This may result in mirror spikes, but we do want to secure
   cold/stale-booted systems as soon as possible.

  [Test Case]

   * Run system for more than 24h, and check that apt updates were
     automatically executed twice.

   * Check that unattended upgrades were triggered to be applied at
     6am..7am window, if any.

   * Poweroff the machine over the period when apt-get update was
     scheduled, poweron and observe that apt-get update / download / 
 unattended upgrade are all performed on boot.

  [Regression Potential]

   * The newly proposed behavior is a mix of Pre-xenial behavior of "do
     everything at 6am..6:30am window" and the xenial+ behavior of "do 
 everything at random times throughout the day". If there are specific 
 deployments that rely on the previous types of behaviour they will be 
 able to adjust manually the systemd timers with the overrides to be 
 executed exactly as they wish; or match the .0 release behaviour that 
 they preffer.

   * If timers behavior is coded wrongly the proposed behaviour might not be
     executed as intended, thus requiring further SRUs to bring us in-line
     with the great expectations.
