AttributeError: 'NoneType' object has no attribute 'write'
+
+ After working on https://bugs.launchpad.net/apport/+bug/1732962, the error
tracker started throwing the error above.
+ it appears that print_usage is called and throwing an error because in this
context (called with core_pattern) apport doesn't have an stdout or stderr.
after looking at traces it seems the kernel is adding 'deleted' to the name of
the process which cause argument parsing to fail.
+
+ The fix below from bdmurray seems to fix it.

+
+ There is report of this issue in Focal, Bionic and xenial
** Changed in: apport (Ubuntu)
