[Bug 1624644] Re: By default settings unattended-upgrade does not automatically remove packages that become unused in conjunction with updating by other software

Thu Mar 1 16:32:49 UTC 2018

This bug was fixed in the package unattended-upgrades - 1.0ubuntu1

---------------
unattended-upgrades (1.0ubuntu1) bionic; urgency=medium

  * Merge from Debian unstable
    - Remaining changes:
      - unattended-upgrades: Do not automatically upgrade the development
        release of Ubuntu unless Unattended-Upgrade::DevRelease is true.
    - Dropped changes, included in Debian:
      - Run upgrade-between-snapshots only on amd64.
        The test exercises only unattented-upgrade's Python code and uses
        dependencies from the frozen Debian snapshot archive thus running
        it on all architectures would provide little benefit.

unattended-upgrades (1.0) unstable; urgency=medium

  [ Simon Arlott ]
  * Revert sending mails on WARNINGS when in MailOnlyOnError mode"
  * 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.
  * Add .gitignore and debian/.gitignore
  * Remove bzr configuration.
    This is unnecessary now that u-u is in git.

  [ Michael Vogt ]
  * unattended-upgrades: tweak mail-on-warnings PR
  * unattended-upgrade: extract is_autoremove_valid helper

  [ Balint Reczey ]
  * Run upgrade-between-snapshots only on amd64.
    The test exercises only unattented-upgrade's Python code and uses
    dependencies from the frozen Debian snapshot archive thus running
    it on all architectures would provide little benefit.
  * 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

Bug description:
  When using default settings for unattended-upgrade i.e.
  Unattended-Upgrade::Remove-Unused-Dependencies "false";
  # default "false"
  Unattended-Upgrade::Remove-New-Unused-Dependencies "true";
  # default "true"
  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  unattended-upgrade is unable to remove packages that become unused in conjunction with updating by other software such as update-manager or apt full-upgrade. This is because unattended-upgrade compares the list of unneeded packages before and after it upgrades packages to detect which packages are new unused ones.

  Consequently, if user installs new kernels using e.g. update-manager,
  the excessive kernels will not be removed by unattended-upgrade, and
  eventually (small) /boot will become full.

  Expected behavior: handle removing of unused packages differently at
  least until other package management software installed by default can
  handle removing of new unused packages.
