Bug description:
  Test Case
  ---------

  There should be no instances of

  for the fixed version.

  Original Description
  --------------------

  The Ubuntu Error Tracker has been receiving reports about a problem regarding apport.  This problem was most recently seen with package version 2.20.11-0ubuntu82.1, the problem page at https://errors.ubuntu.com/problem/e714f8181c0785693f3a66969c594a3b19bcab2b contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports.
  If you do not have access to the Ubuntu Error Tracker and are a software developer, you can request it at http://forms.canonical.com/reports/.

  Traceback (most recent call last):
    File "/usr/share/apport/apport", line 531, in <module>
      options = parse_arguments()
    File "/usr/share/apport/apport", line 463, in parse_arguments
      parser.print_usage()
    File "/usr/lib/python3.10/argparse.py", line 2562, in print_usage
      self._print_message(self.format_usage(), file)
    File "/usr/lib/python3.10/argparse.py", line 2573, in _print_message
      file.write(message)
  AttributeError: 'NoneType' object has no attribute 'write'

  This bug can be reproduced by configuring the previously supported
  parameters to Apport and then let a process crash (e.g. call divide-
  by-zero):

  ```
  echo "|/usr/share/apport/apport %p %s %c %d %P %E" | sudo tee /proc/sys/kernel/core_pattern
  ```

  So this bug is a regression of commit c320e910a516 ("Switch to using
  non-positional arguments") which is a fix for CVE-2022-28658 and
  CVE-2021-3899.
