Does this need different kind of verification for Xenial than what I did in Bug #1624644?
** Description changed: [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. + * 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.

[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. ** Tags removed: verification-needed-xenial ** Tags added: verification-done-xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1675079 Title: 16.04 LTS Partition /boot fills up with Kernel images, gets underwear in a twist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1675079/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
