[errors.ubuntu.com bug bridge]

[Impact]
 * The Ubuntu Error Tracker has been receiving reports about a problem regarding apport. This problem was most recently seen with package version 2.20.10-0ubuntu5, the problem page at https://errors.ubuntu.com/problem/64f362ed27e5f6069d78b02c2cbca5c09fcc19ee
 * The theory is that those crashes are trigger by reports generated (but not send) pre apport 2.20.9-0ubuntu7.3. They don't hafe thus the "remember" key, and thus, the new apport, when reporting, is crashing.
 * We now ignore if the key isn't present and just consider the answer as "false", which is a no-op.

[Test Case]
 * Install apport 2.20.9-0ubuntu7.1
 * Generate a crash but don't report it.
 * Upgrade to apport apport 2.20.9-0ubuntu7.3
 * Report this crash.
   -> No apport crash should be triggered

[Regression Potential]
 * We are doing a python2 compatible try/except to ignore the KeyError which was the regression. It doesn't seem it can trigger other regressions.

Here's the Traceback:

Traceback (most recent call last):
  File "/usr/share/apport/apport-gtk", line 598, in <module>
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 709, in run_argv
    return self.run_crashes()
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 265, in run_crashes
    self.run_crash(f)
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 322, in run_crash
    if response['remember']:
KeyError: 'remember'

This was introduced in revision 3204 of apport which has been SRU'ed to Ubuntu 18.04.

(Set it to medium as the thoery is that it's only happening with older, staggering, crashes)

[Brian Murray (brian-murray)]

I received this crash today and I believe it happened because I had closed a previous apport crash dialog by using the "x" in the upper right hand corner.

[Brian Murray (brian-murray)]

Ah actually, I think my apport versions were mismatched. As we can see below python3-apport was updated but apport-gtk and apport were not.

Ok, so the current fix in UNAPPROVED will prevent that at least ;)

I've generated a report with a version pre 7.3, then, upgrade apport and report it with 7.4 and I didn't trigger any crash.

[Łukasz Zemczak (sil2100)]
