[Bug 1157746] Re: Old kernels are not being listed by autoremove (regression)

[Steve J.]

Hi Folks,

Looks like this is on my end. My organization uses FAI (fai-project.org)
to automate ubuntu installs, and it's installing the kernel packages so
that they are marked as manually installed (and later updates to the
kernel package don't change that). Adding a postinstall script to change
the flag to automatic makes the apt-auto-removal stuff work as expected.

Title:
  Old kernels are not being listed by autoremove (regression)

Status in “aptdaemon” package in Ubuntu:
  Invalid

Bug description:
  Hello,

  A patch was released in this bug report, which added a script to mark
  old/unused kernels as autoremoveable:
  https://bugs.launchpad.net/ubuntu/+source/apt/+bug/923876

  I've upgraded apt to version 0.8.16~exp12ubuntu10.10, and I see the
  new addition of the /etc/kernel/postinst.d/apt-auto-removal script,
  and it seems to be called correctly when upgrading, and it generates a
  /etc/apt.conf.d/01-autoremove-kernels file as expected, with the
  following contents:

  // File autogenerated by /etc/kernel/postinst.d/apt-auto-removal, do not edit
  APT
  {
    NeverAutoRemove
    {
      "^linux-image-3.2.0-38-generic$";
      "^linux-image-extra-3.2.0-38-generic$";
      "^linux-signed-image-3.2.0-38-generic$";
      "^linux-backports-modules-.*-3.2.0-38-generic$";
      "^linux-headers-3.2.0-38-generic$";
      "^linux-image-3.2.0-39-generic$";
      "^linux-image-extra-3.2.0-39-generic$";
      "^linux-signed-image-3.2.0-39-generic$";
      "^linux-backports-modules-.*-3.2.0-39-generic$";
      "^linux-headers-3.2.0-39-generic$";
    };
  };

  However, upon running 'apt-get autoremove' as suggested in the bug
  report mentioned above, kernel versions prior to 3.2.0-38 are not
  offered for removal. I see this on several Ubuntu hosts running
  Precise (Ubuntu 12.04.2 LTS). Are we looking at some sort of
  regression?
