[Bug 2018128] Re: Apport does not collect all logs when the package is HWE kernel (or any derivative)

[Juerg Haefliger]

I cannot possible test all newly added kernel source packages. Focus on
linux-latency and verify that additional kernel data (dmesg) is
collected.

1) Test current behavior

Oracular with current linux-base/4.5ubuntu9:

$ sudo ubuntu-bug linux-lowlatency
<snip>
Please choose (S/V/K/I/C): k
Problem report file: /tmp/apport.linux-lowlatency.4q4_bmtk.apport

$ sudo grep -A 10 -i dmesg /tmp/apport.linux-lowlatency.4q4_bmtk.apport
$

Kernel log is *not* collected.

2) Install linux-base/4.5ubuntu9.1 from oracular-proposed

$ apt-cache policy linux-base
linux-base:
  Installed: 4.5ubuntu9.1
  Candidate: 4.5ubuntu9.1
  Version table:
 *** 4.5ubuntu9.1 100
        100 http://archive.ubuntu.com/ubuntu oracular-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     4.5ubuntu9 500
        500 http://archive.ubuntu.com/ubuntu oracular/main amd64 Packages

3) Test new behavior

$ sudo ubuntu-bug linux-lowlatency
<snip>
*** Collecting problem information
Please choose (S/V/K/I/C): k
Problem report file: /tmp/apport.linux-lowlatency.gjzw1v0t.apport

$ sudo grep -A 10 -i dmesg /tmp/apport.linux-lowlatency.gjzw1v0t.apport
CurrentDmesg:

Bug description:
  [ Impact ]

  Ubuntu 22.04 LTS with kernel 5.19.0-41-generic

  When filing bugs against the package 'linux' apport collects all the logs needed
  to the kernel

  But in case the user is not on stock kernel anymore and has the HWE kernel
  apport only imports 2 logs Dependencies.txt + ProcCpuInfoMinimal.txt

  and forwards the package 'linux' towards linux-signed-hwe-5.19 (in my
  case)

  would it be possible to make apport collect all the logs needed in all
  kernel cases?

  ProblemType: Bug

  Package: apport 2.20.11-0ubuntu82.4
  ProcVersionSignature: Ubuntu 5.19.0-41.42~22.04.1-generic 5.19.17

  UpgradeStatus: No upgrade log present (probably fresh install)

  [ Test Plan ]

  Install a derivative kernel, run 'ubuntu-bug linux-<foo>' and check
  that all necessary logs are collected.

  [ Where Problems Could Occur ]

  The fix adds additional source package hooks and removes some stale
  ones. Potential issue are log collection/upload problems.
