Bug description:
  [Impact]

   * Update-manager and unattended-upgrades install many kernel packages during 
the lifetime of a release but does not remove them automatically leading to 
those packages filling disk space potentially completely filling /boot and 
making the system unable to install updates or even boot.
   * Stable release users are impacted by this bug for years and their systems 
already collected many autoremovable unused kernel packages, thus they would 
benefit from backporting the fix greatly.
   * The bug is fixed by removing autoremovable (not currently booted) kernel 
packages when running unattended-upgrades or update-manager. Update manager 
offers the kernel removals when there are other updates to be installed.

  [Test Case]

   1. Install kernel packages to be removed, mark them auto-installed
  and run apt's kernel hook script to make apt consider them
  autoremovable:

    sudo apt install -y linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
    sudo apt-mark auto linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
    sudo /etc/kernel/postinst.d/apt-auto-removal

   2. Also downgrade a package to be upgraded:

     sudo apt-get install -y --allow-downgrades ca-
  certificates=20160104ubuntu1

   3. (update-manager). Run update-manager and observe that kernel
  packages are offered for removal in Details of updates.

    sudo update-manager

   4. (update-manager) Click on Install Now and observe that the kernel
  packages are removed.

   3. (unattended-upgrades, the fix comes in an update of u-u) Run
  unattended-upgrades manually and observe the removal of the
  autoremovable kernel packages:

    sudo unattended-upgrade -v

  [Regression Potential]

   The change may cause update-manager or unattanded-upgrades to remove
  used kernel packages or fail to install other package updates.

  [Other Info]

  The unattended-upgrades fix is uploaded with many other fixes and
  those may cause regressions in other areas in unattended-upgrades.

  [Original bug text]

  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.

  [Impact]

   * Update-manager and unattended-upgrades install many kernel packages during 
the lifetime of a release but does not remove them automatically leading to 
those packages filling disk space potentially completely filling /boot and 
making the system unable to install updates or even boot.
   * Stable release users are impacted by this bug for years and their systems 
already collected many autoremovable unused kernel packages, thus they would 
benefit from backporting the fix greatly.
   * The bug is fixed by removing autoremovable (not currently booted) kernel 
packages when running unattended-upgrades or update-manager. Update manager 
offers the kernel removals when there are other updates to be installed.

  [Test Case]

   1. Install kernel packages to be removed, mark them auto-installed
  and run apt's kernel hook script to make apt consider them
  autoremovable:

    sudo apt install -y linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
    sudo apt-mark auto linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
    sudo /etc/kernel/postinst.d/apt-auto-removal

   2. Also downgrade a package to be upgraded:

     sudo apt-get install -y --allow-downgrades ca-
  certificates=20160104ubuntu1

   3. (update-manager). Run update-manager and observe that kernel
  packages are offered for removal in Details of updates.

    sudo update-manager

   4. (update-manager) Click on Install Now and observe that the kernel
  packages are removed.

   3. (unattended-upgrades, the fix comes in an update of u-u) Run
  unattended-upgrades manually and observe the removal of the
  autoremovable kernel packages:

    sudo unattended-upgrade -v

  [Regression Potential]

   The change may cause update-manager or unattanded-upgrades to remove
  used kernel packages or fail to install other package updates.

  [Other Info]

  The unattended-upgrades fix is uploaded with many other fixes and
  those may cause regressions in other areas in unattended-upgrades.

  [Original bug text]

  When using default settings for unattended-upgrade i.e.
  Unattended-Upgrade::Remove-Unused-Dependencies "false";
  # default "false"
  Unattended-Upgrade::Remove-New-Unused-Dependencies "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

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

[Łukasz Zemczak]

Can anyone potentially perform verification of the artful packages? We
usually prefer releasing packages for newer series first, although it's
not really a big deal right now because xenial -> artful is not an
official upgrade path anymore.

@jarnos Verification is needed only for update-manager for now, thus I
think you verified that the fix worked for Xenial. Could you please
change the tag to reflect that or you would like to wait for the u-u
fix, - which may come later?

  When using default settings for unattended-upgrade i.e.

  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  unattended-upgrade is unable to remove packages that become unused in

unused ones.

[Jarno Suni]

Yes, it is good that update-manager can do removing, as that is what
most people use anyway.  linux-purge might still have some use e.g. if
for some reason /boot becomes full, or there are non-autoremovable
kernel packages (which may happen in 14.04 even with kernels installed
using update-manager Bug #1439769).

Thanks for testing the fix and also thank you for preparing the
linux-purge script. I read it but integrating it to to current tools
would have been problematic and I hope you agree that the solution
finally used is minimally intrusive and achieves removing unused
kernels in a safe way.

The fix for unattended-upgrades is not uploaded yet but is available
Bionic and in the ppa:rbalint/scratch PPA if you would like to give it
a try.

Brian, I tested the update-manager version you told. It is true that
update-manager removes the unused packages, but step 3. (unattended-
upgrades) does not remove the unused kernels.

I add failed tag as this bug is originally about unattended-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.

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

[Brian Murray]

Hello Jarno, or anyone else affected,

Accepted update-manager into artful-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
manager/1:17.10.14 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-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. 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!

Bug description:
  [Impact]

   * Update-manager and unattended-upgrades install many kernel packages during 
the lifetime of a release but does not remove them automatically leading to 
those packages filling disk space potentially completely filling /boot and 
making the system unable to install updates or even boot.
   * Stable release users are impacted by this bug for years and their systems 
already collected many autoremovable unused kernel packages, thus they would 
benefit from backporting the fix greatly.
   * The bug is fixed by removing autoremovable (not currently booted) kernel 
packages when running unattended-upgrades or update-manager. Update manager 
offers the kernel removals when there are other updates to be installed.

  [Test Case]

   1. Install kernel packages to be removed, mark them auto-installed
  and run apt's kernel hook script to make apt consider them
  autoremovable:

sudo apt install -y linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
sudo apt-mark auto linux-image-extra-4.4.0-92-generic 
linux-image-extra-4.4.0-93-generic
sudo /etc/kernel/postinst.d/apt-auto-removal

   2. Also downgrade a package to be upgraded:

 sudo apt-get install -y ca-certificates=20160104ubuntu1

   3. (update-manager). Run update-manager and observe that kernel
  packages are offered for removal in Details of updates.

sudo update-manager

   4. (update-manager) Click on Install Now and observe that the kernel
  packages are removed.

   3. (unattended-upgrades) Run unattended-upgrades manually and observe
  the removal of the autoremovable kernel packages:

sudo unattended-upgrade -v

  [Regression Potential]

   The change may cause update-manager or unattanded-upgrades to remove
  used kernel packages or fail to install other package updates.

  [Other Info]
   
  The unattended-upgrades fix is uploaded with many other fixes and those may 
cause regressions in other areas in unattended-upgrades.

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

  the excessive kernels will not be removed by unattended-upgrade, and

Status in update-manager source package in Artful:
  New

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.
