This is causing me trouble building a focal (20.04) userspace from
scratch:
$ dpkg --configure -a
[...]
Setting up apt (2.0.8) ...
/var/lib/dpkg/info/apt.postinst: 65:
/etc/kernel/postinst.d/apt-auto-removal: not found
dpkg: error processing package apt (--configure):
installed apt package post-installation script subprocess returned error
exit status 127
It works with apt 2.0.6.
I think it's because the patch[1] removes `/etc/kernel/postinst.d/apt-
auto-removal`:

Since I'm building this from scratch, "$2" (the most-recently-

true.

Title:
Only keep 2 kernels
Status in apt package in Ubuntu:

Bug description:
[Impact]
APT currently keeps 3 kernels or even 4 in some releases. Our boot partition
is sized for a steady state of 2 kernels + 1 new one being unpacked, hence
users run out of space and new kernels fail to install, upgrade runs might
abort in the middle. It's not nice.
[Test plan]
1. Have two kernels installed (let's call them version 3, 2)
2. Check that both kernels are not autoremovable
3. Install an old kernel (let's call it 1), and mark it automatic
4. Check that 1 will be autoremovable (apt autoremove -s)
5. Reboot into 1, check that 2 is autoremovable (apt autoremove -s)
6. Actually remove 2
7. Reboot into 3 and check that both 1 and 3 are now not autoremovable
[Where problems could occur]
We could keep the wrong kernels installed that the user did not expect.
We remove the requirement to keep the most recently installed version,
previously recorded in APT::LastInstalledKernel, to achieve this, as
we had 3 hard requirements so far:
1. keep booted kernel
2. keep highest version
3. keep most recently installed
1 can't be removed as it would break running systems, 2 is what you
definitely want to keep.
During normal system lifetime, the most recently installed kernel is
the same as the highest version, so 2==3, and there are no changes to
behavior.
Likewise, if you most recently installed an older kernel manually for
debugging, it would be manually installed and not subject to removal,
even if the rule is dropped.
The behavior really only changes if you install an older kernel, and
then mark it auto - that older kernel becomes automatically removable
immediately after it is marked as auto.
