Why does the update-manager upload include this code?:
+ running_kernel_version = subprocess.check_output(
+ ["uname", "-r"], universal_newlines=True).rstrip()
+ self.running_kernel_pkgs_regexp = re.compile("(" + "|".join(
+ [("^" + p + ".*" + running_kernel_version)
+ if not p.startswith(".*") else (running_kernel_version + p)
+ for p in apt_versioned_kernel_pkgs]) + ")")
[...]
+ if (pkg.is_auto_removable and
+ (cache.versioned_kernel_pkgs_regexp and
+ cache.versioned_kernel_pkgs_regexp.match(pkg.name) and
+ not cache.running_kernel_pkgs_regexp.match(pkg.name))):
+ kernel_autoremove_pkgs.append(pkg)
+ pkg.mark_delete()
apt already has an implementation in /etc/kernel/postinst.d/apt-auto-
removal which ensures that the currently-running kernel is not
autoremoved. Why are you duplicating this functionality in update-
manager?

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.
[Original bug text]
On a 16.04LTS system, the /boot partition will eventually fill with
Kernel images, until the point where "apt-get autoremove" can't
complete.
This issue has previously been reported as fixed, but it is not fixed:
https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1357093
Generally what I see is the final kernel image that fills the drive is
incompletely installed (the header package does not make it). "apt-
get autoremove" tries to work, but fails. I must manually remove
kernel images to free enough space.
I see this on a machine used by my elderly parents, where 'Download
and install updates automatically' is set. And on my home machines,
where the setting is elsewhere.
