[Bug 356101] Re: apport-retrace: try older debug package versions

 

Launchpad now has support for debug symbol packages and apport also
check's for older package versions in Launchpad.  I believe the fixes
for this bug were made in the following merge proposal.

Title:
  apport-retrace: try older debug package versions

Status in apport package in Ubuntu:
  Triaged

Bug description:
  It is the second time now that the apport retracing service tells me:
  "Crash report cannot be processed" and
  "However, processing it in order to get sufficient information for the
  developers failed (it does not generate an useful symbolic stack trace). This
  might be caused by some outdated packages which were installed on your system
  at the time of the report:"
  However. Before and after the incident happenend, I had updated the whole system. So I can not do anything do help and to see if the bug still occurs with newer packages because they can not be installed. At least I do not know how.

  This kind of problem has three main sources:

   * Retracers being broken for an extended period of time, as happened
  during Oneiric. Hopefully with the rewritten apport-retrace this
  should now happen a lot less often, as we dropped the dependency to
  the fragile fakechroot.

    There is no single "fix" for this, it's a question of continuously
  maintaining the retracers.

   * debug symbols missing. This is mostly a problem of Launchpad not
  supporting debug symbol packages yet, and our hack for
  fetching/publishing them just fails occasionally. This is not a bug in
  apport itself, but in how ddeb packages are handled in
  Launchpad/Ubuntu.

   * apport-retrace not trying to install older versions of packages,
  mostly because apt does not support this really. However, we can apply
  some hackery to work around this in principle. This is what the bug
  title says, and what is actually actionable in apport itself.
