Comment 4 for bug 1820132

Here's the better changelog entry:

apport (2.20.10-0ubuntu24) disco; urgency=medium

  * debian/control: apport-gtk should depend on whoopsie-preferences as that
    is needed to store preferences for reporting crashes. (LP: #1809247)
  * apport/report.py, apport/ui.py: raise ValueError if the pid is not
    accessible, display an error message for that or an invalid pid. (LP: #1396160)
  * switch from pyflakes to pyflakes3, drop some python2 code
  * apport/report.py: Have add_gdb_info return a FileNotFoundError if gdb or
    the crashing executable are not found and modify whoopsie-upload-all to
    upload crashes in that situation. (LP: #1820132)
  * debian/control, apport/hookutils.py: pkexec does not work in non-graphical
    environments yet (LP #1821415) and its providing package should only be
    a suggests because gathering of information as root isn't entirely
    necessary for a bug report.
