This bug was fixed in the package unattended-upgrades -
1.1ubuntu1.18.04.7~16.04.2

---------------
unattended-upgrades (1.1ubuntu1.18.04.7~16.04.2) xenial; urgency=medium

  * Don't check blacklist too early and report updates from not allowed origins
    as kept back. (LP: #1781176)
  * test/test_blacklisted_wrong_origin.py: Fix and enable test
  * Filter out progress indicator from dpkg log (LP: #1599646)
  * Clear cache when autoremoval fails (LP: #1779157)
  * Find autoremovable kernel packages using the patterns in APT's way
    (LP: #1815494)

  * Start service after systemd-logind.service to be able to take inhibition
    lock (LP: #1806487)
  * Handle gracefully when logind is down (LP: #1806487)

unattended-upgrades (1.1ubuntu1.18.04.7~16.04.0) xenial; urgency=medium

  * Backport to Xenial (LP: #1702793)
  * Revert to build-depending on debhelper (>= 9~) and dh-systemd
  * Revert configuration example changes to avoid triggering a debconf question
  * debian/postinst: Update recovery to be triggered on Xenial's package 
versions

unattended-upgrades (1.1ubuntu1.18.04.7) bionic; urgency=medium

  * Trigger unattended-upgrade-shutdown actions with PrepareForShutdown()
    Performing upgrades in service's ExecStop did not work when the upgrades
    involved restarting services because systemd blocked other stop/start
    actions making maintainer scripts time out and be killed leaving a broken
    system behind.
    Running unattended-upgrades.service before shutdown.target as a oneshot
    service made it run after unmounting filesystems and scheduling services
    properly on shutdown is a complex problem and adding more services to the
    mix make it even more fragile.
    The solution of monitoring PrepareForShutdown() signal from DBus
    allows Unattended Upgrade to run _before_ the jobs related to shutdown are
    queued thus package upgrades can safely restart services without
    risking causing deadlocks or breaking part of the shutdown actions.
    Also ask running unattended-upgrades to stop when shutdown starts even in
    InstallOnShutdown mode and refactor most of unattended-upgrade-shutdown to
    UnattendedUpgradesShutdown class. (LP: #1778219)
  * Increase logind's InhibitDelayMaxSec to 30s. (LP: #1778219)
    This allows more time for unattended-upgrades to shut down gracefully
    or even install a few packages in InstallOnShutdown mode, but is still a
    big step back from the 30 minutes allowed for InstallOnShutdown previously.
    Users enabling InstallOnShutdown node are advised to increase
    InhibitDelayMaxSec even further possibly to 30 minutes.
    - Add NEWS entry about increasing InhibitDelayMaxSec and InstallOnShutdown
      changes
  * Ignore "W503 line break before binary operator"
    because it will become the best practice and breaks the build
  * Stop using ActionGroups, they interfere with apt.Cache.clear()
    causing all autoremovable packages to be handled as newly autoremovable
    ones and be removed by default. Dropping ActionGroup usage does not slow
    down the most frequent case of not having anything to upgrade and when
    there are packages to upgrade the gain is small compared to the actual
    package installation.
    Also collect autoremovable packages before adjusting candidates because that
    also changed .is_auto_removable attribute of some of them. (LP: #1803749)
    (Closes: #910874)

unattended-upgrades (1.1ubuntu1.18.04.6) bionic; urgency=medium

  * Unlock for dpkg operations with apt_pkg.pkgsystem_unlock_inner() when it is
    available. Also stop running when reacquiring the lock fails.
    Thanks to Julian Andres Klode for original partial patch (LP: #1789637)
  * Skip rebuilding python-apt in upgrade autopkgtests.
    Python-apt has a new build dependency making the rebuilding as is failing
    and the reference handling issue is worked around in unattended-upgrades
    already. (LP: #1781586)
  * Stop trying when no adjustment could be made and adjust package candidates
    only to lower versions (LP: #1785093)
  * Skip already adjusted packages from being checked for readjusting.
    This makes it clearer that the recursion ends and can also be a bit quicker.
    (LP: #1785093)

  * Clear cache when autoremoval is invalid for a package set marked for
    removal and clear cache after failed commits to return from a possibly
    invalid state (LP: #1779157)
  * Don't start or gracefully stop upgrade on battery (LP: #1773033)
  * Skip updates on metered connections (Closes: #855570) (LP: #1781183)
  * Add debian/tests/upgrade-all-security to install all current security

    - Measure time of running with --dry-run in autopkgtests
  * Skip starting init.d script in debhelper-generated postinst part
    (LP: #1778800)

  [ Ivan Kurnosov ]
  * Fixed is_pkgname_in_blacklist to be side-effect free. (LP: #1781176)
    Otherwise 'is_pkgname_in_blacklist' mutates the 'pkgs_kept_back' and
    'unattended-upgrades' treats the package as a blacklisted candidate

  [ Michael Vogt ]
  * unattended-upgrades: fix Unlocked context manager. (LP: #1602536)
    The Unlocked context manager did correctly unlock but did not
    reacquire the lock which means that in minimal-upgrade step
    mode it is possible to run apt code without a lock. If something
    else (like landscape, apt, synaptic, packagekit) locks the cache
    in the meantime this will work and u-u will get dpkg errors
    because dpkg will not be able to perform its operations. It is
    less of an issue in non-minimal mode, but even then the auto-remove
    step may fail in this way.

  * Fix adjusting candidates (LP: #1775292)
  * Relock apt lock before reopening the cache (LP: #1602536)
  * Fix crashing while adjusting candidates and save candidates to adjust only

    too
  * upgrade-between-snapshots: Remove packages installed as the side-effect of
    updating apt and python-apt
  * Ignore errors from compiling backported packages
  * Make is_autoremove_valid() nondestructive.
    Also fix autoremoval of packages when one package can't be removed and
    keeps back other package removals due to missing cache.clear()
  * Fix tracking removed packages

    - Dropped changes, included in Debian:

        The test exercises only unattented-upgrade's Python code and uses

  * Consider conffile prompts to be errors (Closes: #852465)
    Flag packages that have to be upgraded manually because of a conffile
    prompt and consider this to be an error when sending email or exiting.

  [ Simon McVittie ]
  * Add python, python3, setuptools, DistutilsExtra to Build-Depends.
    They are needed for `clean`, so Build-Depends-Indep is not enough.

  * Clean up processes started for getting md5 sums
  * Don't keep /var/lib/dpkg/status open multiple times
  * Adjust candidates in UnattendedUpgradesCache.open()
  * Perform autoremovals in minimal steps, too.
    Also add check to remove only the set of packages selected for autoremoval.
    Without that check unattended-upgrades when (by default) configured to
    remove newly unused packages could also remove auto removable packages
    which were unused before starting starting the upgrade step.
  * Remove unused automatically installed kernel packages
    (LP: #1357093, #1624644, #1675079, #1698159)
  * Stop including Python syntax in the report (Closes: #876796)
  * Do not auto remove packages related to the running kernel (LP: #1615381)
  * Check packages to be autoremoved against blacklists, whitelists.
    Also check if the packages are held.
  * Report package removals in the summary email (Closes: #876797)
  * Run upgrade-between-snapshots test with debugging enabled
  * Don't create new UnattendedUpgradesCache for checking for autoremovals
    .open() refreshes the state in each cache_commit(), this is enough
  * Update .pot and .po files
  * Update .travis.yml to actually build and test u-u from the repo
  * Run only a simple installation test on Travis, the system upgrade
    test was always failing

  * Fix Raspbian default config codename matching.
    Using `archive=${distro_codename}` does not match, at least not in
    Raspbian Stretch anymore. Changing it to `codename=${distro_codename}`.
    I tested that it now works and did not notice any regressions.
    Same change was made to the Debian-specific configuration 3 years ago,
    see commit 9a2afa5.
  * Enable RPi-specific upgrades on Raspbian.
    In addition to the Raspbian repository, Raspbian images distributed by
    the Raspberry Pi Foundation (RPF) depend on the RPF repository for
    kernel and firmware updates.
    This commit adds a pattern matching line for packages from the RPF
    repository to the Raspbian config file for unattended-upgrades.

    invalid (LP: #1737717)
  * Exit when an apt error prevents checking a package for conffile prompt
  * Install upgrades from ${distro_codename}, label=Debian by default.
    This enables updates from stable point releases but also lets testing
    and sid being updated with the package updates.
    Fixes #33. (Closes: #787945, #597061)
  * Fix debian/NEWS.Debian's format
  * Add NEWS item about unattended-uprades installing stable/all updates
  * Stop asking debconf question about Origins-Pattern.
    50unattended-upgrades now contains multiple origins by default and setting
    them from debconf can't be made really easy. Users should change the
    configuration file itself instead. (LP: #1577215)
  * Update PO files about debconf templates
  * Don't log exceptions which did not happen
  * Add autopkgtest for upgrading unstable between two snapshots from
    snapshot.d.o
  * Remove tabs from Debian's configuration file
  * Catch SystemError instead of apt_pkg.Error for backwards compatibility
  * Check in autopkgtest if unattended-upgrades mark additional packages as
    manually installed
  * Test upgrading a full system with desktop packages in autopkgtest.
    Also pick different shapshots with which does not contain
    broken packages.
  * Test sending email after upgrading a full system
  * Show "please don't turn off the computer" while installing updates on
    shutdown.
    This is more informational for users than the original "sleeping for 5s".
    Thanks to Mario Loderer for the suggestion (LP: #1741579)
  * Use eatmydata for system upgrade autopkgtest
  * Run upgrade-between-snapshots autopkgtest even on other distros
  * Apt install built u-u in snapshot upgrade test

    (Closes: #886803)
  * Refresh cache after committing changes to avoid reinstalling packages
    (Closes: #875383)
  * Relax calculating truly minimal sets to sets expected to be minimal.
    This speeds up calculation by making it from ~O(n^2) to ~O(n) at the
    expense of creating slightly bigger sets in rare cases.

      - unattended-upgrades: Do not automatically upgrade the development

    - Dropped changes, included in Debian:
      - Cherry-pick 2e5deed, f26edb4 from upstream to add support for a
        --download-only option, enabling us to download updates at a random
        time of day by default but apply them predictably in the 6am-7am
        window.
      - Fix PEP8 failures (replace except: with except Exception:)
      - unattended-upgrades: Provide some information and create a log entry
        when there is a failure to parse the allowed origins.
      - Add UbuntuESM to the list of sources automatically upgraded from by
        default.
      - Complete the solution for the unattended-upgrades.service unit not
        correctly working
      - d/rules : Remove the override_dh_installinit. The stop option is no
        longer available so the command falls back to default. This is the
        normal behavior so the override is not required
      - d/unattended-upgrades.init : Add Default-Start runlevels, otherwise
        the unattended-upgrades.service unit cannot be enabled on boot
      - d/postinst : Cleanup the stop symlinks created by the wrong
        override_dh_installinit. Without that, the systemd unit cannot be
        enabled correctly.
        Force disable the service before deb-systemd-helper runs so the old
        symlink is not left dangling (workaround for Debian Bug #797108).
        Force enable and start of the systemd unit to work around Debian Bug
        #797108 which fails to enable systemd units correctly when
        WantedBy= statement is changed which is the case here.
      - d/unattended-upgrades.service : Fix the service so it runs correctly on
        shutdown :
        - Remove DefaultDependencies=no : Breaks normal shutdown dependencies
        - Set After= to network.target and local-fs.target. Since our service
          is now ExecStop, it will run before network and local-fs become
          unavailable.
        - Add RequiresMountsFor=/var/log /var/run /var/lib /boot : Necessary if
          /var is a separate file system. Set WantedBy= to multi-user.target
      - Add DEP8 tests to verify the following :
        - Verify that the unattended-upgrades.service unit is enabled and
          started.
        - Verify that InstallOnShutdown works when configured.
      - The systemd unit needs to be an ExecStop since it is is activated on
        shutdown. Otherwise, it will get scheduled after completion of
        the local-fs.target. In the case where /var is a separate
        filesystem, unattended-upgrade-shutdown will hang until timeout
        since /var/run is expected but no longer there
      - When performing a sanity check for packages to install or upgrade
        return false when either there are no packages in the cache or the
        package to upgrade is not in the change set.
      - Do not mark packages for deletion / autoremoval if unattended-upgrades
        is being run in dry-run mode.
      - Store delay command line option as an int not a string since we do
        maths with it.

  * Fix the unattended-upgrades.service unit not correctly working:
    - d/rules : Remove the override_dh_installinit. The stop option is no longer
      available so the command falls back to default. This is the normal
      behavior so the override is not required
    - d/unattended-upgrades.init : Add Default-Start runlevels, otherwise the
      unattended-upgrades.service unit cannot be enabled on boot
    - d/postinst : Cleanup the stop symlinks created by the wrong
      override_dh_installinit. Without that, the systemd unit cannot be
      enabled correctly.
      Force disable the service before deb-systemd-helper runs so the old
      symlink is not left dangling (workaround for Debian Bug #797108).
      Force enable and start of the systemd unit to work around Debian Bug
      #797108 which fails to enable systemd units correctly when WantedBy=
      statement is changed which is the case here.
    - d/unattended-upgrades.service : Fix the service so it runs correctly on
      shutdown :
        Remove DefaultDependencies=no : Breaks normal shutdown dependencies
        Set After= to network.target and local-fs.target. Since our service is
        now ExecStop, it will run before network and local-fs become
        unavailable. Add RequiresMountsFor=/var/log /var/run /var/lib /boot :
        Necessary if /var is a separate file system. Set WantedBy= to
        multi-user.target
    - Add DEP8 tests to verify the following :
      Verify that the unattended-upgrades.service unit is enabled and started.
      Verify that InstallOnShutdown works when configured.

Title:
  Skip updates on metered connections

Status in unattended-upgrades package in Ubuntu:
  Fix Released
Status in unattended-upgrades source package in Xenial:
  Fix Released
Status in unattended-upgrades source package in Bionic:
  Fix Released
Status in unattended-upgrades package in Debian:
  Fix Released

Bug description:
  [Impact]

   * Systems running unattended-upgrades may download updates over
  metered connections causing excessive data usage possibly making users
  being charged for the downloads.

   * Avoiding users being unexpectedly charged due to unattended-
  upgrades' activity warrants an SRU, IMO.

   * The fix uses
  NetworkMonitor.get_network_metered(NetworkMonitor.get_default()) for
  deciding if the connection is metered and skips or gracefully stops
  updates.

  [Test Case]

   * Run "unattended-upgrades --dry-run --verbose" on metered connection
     - The unfixed versions should provide the following output with default 
configuration:
  $ sudo unattended-upgrade --dry-run --verbose 
  Initial blacklisted packages: 
  Initial whitelisted packages: 
  Starting unattended upgrades script
  Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, 
o=UbuntuESM,a=bionic
  No packages found that can be upgraded unattended and no pending auto-removals

     - The fixed versions should provide the following output with default 
configuration:
  Initial blacklisted packages: 
  Initial whitelisted packages: 
  Starting unattended upgrades script
  Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, 
o=UbuntuESM,a=bionic
  System is on metered connection, stopping
   
    - You can check if the default route is on metered connection by running:
  nmcli -t -f GENERAL.DEVICE,GENERAL.METERED dev show `ip route list 0/0 | sed 
-r 's/.*dev (\S*).*/\1/g'`

    - Also run fixed u-u on not metered connection to check if it still works. 
U-u in lxc for example does not detect the connection to be metered.
    - Check if the following configuration can enable updates even on metered 
connections:
  $ cat /etc/apt/apt.conf.d/51unattended-upgrades-metered 
  Unattended-Upgrade::Skip-Updates-On-Metered-Connections "false";

  [Regression Potential]

   * Unattended-upgrades may skip updates even on not metered connections or 
crash, but those are not likely.
   * U-u also adds two new dependencies with the fix which can be seen as a 
regression, but those packages exist on most Ubuntu installations already. (The 
packages are: gir1.2-glib-2.0 and python3-gi)
