The issue is that we have no idea what you're referring to here as
"client-side duping".  We have bug patterns, which tell apport not to file a
bug report but direct the user to a web page instead; but there is no bug
pattern in place for this bug.  There's the apport crash retracer which
identifies duplicates, but that only happens *after* a new bug report has
been filed, and we see no record of new bug reports being filed.

So we frankly have no idea what you're seeing, because it doesn't match the
developers' understanding of how apport works.  I think you will need to
walk us through, page-by-page and quoting word for word, what you see on
your system when the crash report appears, so we can understand exactly
what's going on.

Bug #628104 has new comments, but it has never had a bug pattern and there
are no duplicate bugs against it since May 2011.  Bug #855394 had a bug
pattern which was being used to track hits, and received none from January
to the end of March.  So while I believe that apport directed you here, I
don't know *how*, and we need to fix that so that we can get good, fresh
crash reports from the users who are seeing the issue.

Title:
  aptdaemon crashes during update-manager run: "Could not cancel
  transaction"

Status in “aptdaemon” package in Ubuntu:
  Incomplete

Bug description:
  This crash is the subject of bug 628104 and bug 855394.  Those are
  marked fixed but it's still happening.  The latter bug was closed,
  with this comment:

    "As we have not received any duplicates of this bug since January
  and the bug pattern has received no hits, I am going to mark this bug
  report as Fix Released for Precise and set the Oneiric task to Won't
  Fix. In the event that anyone encounters this bug in the future please
  report a new crash report."

  This is that bug report. :)

  bug 628104 was really fixed."

  That might be true.

  A number of users have tried to report the crash through apport, but
  the traceback has always been duped to bug 628104.  Which none of us
  can re-open.

  I myself cannot reproduce it.  The recent information is all at
  628104.  Thanks.
