apport does not depend on gdb so it's possible, even likely, that gdb is not installed on the system reporting the crash. Subsequently, report.add_gdb_info will fail and the docstring indicates that this should "Raises ... OSError if calling gdb fails" however the docstring is currently a liar perhaps because of a change I made. Regardless this should be sorted out. Here's the Traceback:

Traceback (most recent call last):
  File "/usr/share/apport/whoopsie-upload-all", line 162, in <module>

Actually, I was looking at the wrong thing what's really missing is the executable which crashed from the top of the function gdb_command:

        assert 'ExecutablePath' in self
        executable = self.get('InterpreterPath', self['ExecutablePath'])

While it makes sense for apport-retrace to have an AssertionError if the executable doesn't exist I don't think whoopsie-upload-all necessarily should just because it isn't on the client system doesn't mean the retracers won't be able to install it.

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

    necessary for a bug report. ...

To test this with whoopsie-upload-all one could do something like the following:

1) xeyes &
2) pkill -11 xeyes
3) sudo mv /usr/bin/xeyes /tmp/
4) /usr/share/apport/whoopsie-upload-all

Don't forget to move xeyes back if you care about it.
