[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.28.1-0ubuntu3.1

---------------
apport (2.28.1-0ubuntu3.1) noble; urgency=medium

  [ Chris Peterson ]
  * d/package-hooks/subiquity.py: update information collection (LP: #2067775)
    - Add information about snap update/refresh state
    - Attach logs and change key names to align with the information
      attached by subiquity's self-collection
    - Attach hardware information
    - Ensure bug reports are always private since there may be private
      information in the logs
    - Don't require sudo for logs collection
    - Add journal logs
    - Ensure snap revision is included in both deb and snap collection
      style
    - Handle version information when permission elevation fails.

Bug description:
  [ Impact ]

  On affected systems, Python crashes will be owned by the crashing
  group instead of whoopsie. This causes whoopsie to fail reading and
  uploading the crash report. So a lot of Python crashes were not
  reporting and keeping us blind.

  [ Test Plan ]

  1. Reconstruct the problem by setting the permission of /var/crash to 1777.
  2. Upgrade Apport to the fixed version
  3. Verify that /var/crash has the permission 3777 after the update.
  4. Run and crash a random Python script (needs to be from a Ubuntu package)
  5. Verify that the Python crash was correctly uploaded.

  [ Where problems could occur ]

  The fix touched the /var/crash permission and the apport.service
  startup code. This might lead to failures on custom setup (despite
  using similar postinst code than whoopsie).

  This fix might still not address the initial bug report of reporting
  crashes in a loop. In this case a follow-up bug report should be
  started.

  [ Original report ]

  /var/crash has the following contents:

  -rw-r----- 1 vorlon   vorlon   107490 May 23 16:05 _usr_bin_gourmand.1000.crash
  -rw-rw-r-- 1 vorlon   vorlon        0 May 23 16:06 _usr_bin_gourmand.1000.upload
  -rw------- 1 whoopsie whoopsie      5 May 23 16:07 _usr_bin_gourmand.1000.uploaded
  -rw-r----- 1 vorlon   vorlon    23647 May 23 13:57 _usr_bin_python-argcomplete-check-easy-install-script.1000.crash
  -rw-rw-r-- 1 vorlon   vorlon        0 May 23 13:59 _usr_bin_python-argcomplete-check-easy-install-script.1000.upload
  -rw------- 1 whoopsie whoopsie      5 May 23 13:59 _usr_bin_python-argcomplete-check-easy-install-script.1000.uploaded

  As seen, the .upload / .uploaded files were created within 2 minutes
  of each of the crashes.

  But after submitting the crash report for /usr/bin/python-argcomplete-
  check-easy-install-script, I left my desktop for a while.  I came back
  to find at least TWENTY dialogs prompting me to submit the same crash
  report.

  The only way to stop the system from creating more prompts is to
  remove these files from disk.
