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) 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.
