Unattended-upgrades and update-manager will remove old unused kernels
with the default configuration.
This is already happening in 18.04 and will be back-ported to 16.04.

No, the /boot partition will be kept, but unused old kernel files will
be cleaned up. Without changing the configuration files from the
shipped default values.

I hope they will be pleased to see that obsolete kernels are removed
without starting terminals. :-)

Seems to be a design flaw rather than a bug.

Happy to discuss and help...in the support forums.
This CLOSED bug report is not the appropriate location to help people 
troubleshoot.

Status in unattended-upgrades package in Ubuntu:

Bug description:

  Once kernel updates start being released this partition soon fills

Jarno Suni,

This bug report ran it's course, and 'Fix Released' is another way of
saying 'Closed.' You can discuss it, but no developer is likely to read
it...to them, it's a closed issue. It's fixed, and won't be unfixed.
The patch is released, and won't be reverted. The normal workflow is to
file a new bug, not to reopen or discuss a closed bug.

Bug 1357093 is 'Fix Released' because I duplicated the original
reporter's problems, triaged the bug, and forwarded enough information
to a developer who agreed with my triage and decided to fix it. Upon
testing the fix (repeatedly), my duplication of the original reporter's
problem is really fixed.

If you have a triage-able problem with the unattended-upgrades package,
please open a new bug report and provide enough information so I can
triage it. I cannot generally triage a problem that I cannot duplicate.

If all you know is 'it should work but does not work', then please jump
into a support forum (like Ubuntuforums) and let the experts there help
you figure out how to duplicate or triage it. Similar symptoms may come
from very different causes. Having an unresolved problem is really,
really frustrating. Been there.

I'm quite happy to discuss kernel header dependencies and go into much
greater detail...but doing so in this bug report would be rather
counterproductive. The issue is closed, and most of the questions seem
unrelated to the original bug.

[Ian Weisser]

Jarno Suni,

That possible cause seems irrelevant to Unattended-Upgrades. Any
package installed by any front-end to apt will be upgraded. U-U doesn't
know what packages are installed, nor care. U-U simply tells aptdaemon
to upgrade packages from the repositories authorized by the user. U-U
does not duplicate nor replace Software Updater, and both can safely be
used.

Try running 'apt autoremove' (16.04) or 'apt-get autoremove'
(12.04/14.04).

If those kernels are not removed, then your problem is the apt-marking, 
not U-U. There are several ways to prevent automatically marking kernel
packages as 'auto' - the most common is by installing kernel header
packages.

If those kernels are removed, then check the U-U logs in /var/log to
ensure that U-U is really operating.

A bug report is an awful place to try to troubleshoot in this way. If
you open a thread on UbuntuForums, we may be able help you better.
