** Description changed:
- Binary package hint: apport-retrace
-
It is the second time now that the apport retracing service tells me:
- Crash report cannot be processed and
+ 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might be caused by some outdated packages which were installed on your system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.
- I see two possible causes for this:
- - Some dependencies on my system which prevent the installation of newer
versions
- - Or apport has access to some non-official repositories I do not know.
- Therefor I think apport should try to figure out what is the cause of
outdated packages:
- - simple update is needed
- - or process the list of installed packages and the sources.list on the users
system and tell him
- a) what repository needs to be added
- or
- b) what packages need to be deinstalled
- to get new packages.
- This could also uncover packaging/ dependency problem like: When I remove
the packages apport suggests my whole Xserver gets removed. Therefore I can not
update packages until this is solved.
+
+ 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.
