The traceback happens when trying to print the usage for the apport
command. However, the real issue is why is apport not being called
correctly. Looking at a few of the crash reports we can see a pattern
similar to the following:
PythonArgs
['/usr/share/apport/apport', '14750', '11', '0', '1', '14750',
'!opt!VBoxGuestAdditions-6.1.4!bin!VBoxClient', '(deleted)']
The "(deleted)" bit is likely coming from the %E part of the core
pattern. From man core.
Since kernel 5.3.0, the pipe template is split on spaces into an
argument list before the template parameters are expanded. In
earlier kernels, the template parameters are expanded first and the
resulting string is split on spaces into an argument list. This
means that in earlier kernels executable names added by the %e and %E
template parameters could get split into multiple arguments. So the
core dump handler needs to put the executable names as the last
argument and ensure it joins all parts of the executable name using
spaces. Executable names with multiple spaces in them are not
correctly represented in earlier kernels, meaning that the core dump
handler needs to use mechanisms to find the executable name.
