Public bug reported:
>From some update last year or so, apt has achived the tools to remove
old Linux kernels via /etc/kernel/postinst.d/apt-auto-removal. This is
really great, but for some reason, all apt tools agree on this (apt-get
autoremove, apt autoremove), but aptitude does not.
For example, here I have an installation where 4.15.0-20 is safe for
deinstallation, and generated by script above config agrees:
$ LANG=C apt --dry-run autoremove
NOTE: This is only a simulation!
apt needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!

Need to get 0 B of archives. After unpacking 178 MB will be freed.

Do you want to continue? [Y/n/?] y
Would download/install/remove packages.
Removing modules-extra seems fine for it, though!
I have looked over all apt configs, there was no sign for me that aptitude was
configured specificly to keep the images.
