||<>|| = Introduction to Apport Retracing Service = [[https://launchpad.net/~apport|Apport Retracing Service]] (ARS) is a [[Launchpad]] bot which automatically provides symbolic stack traces to Launchpad crash reports. When a Ubuntu Community member submits a [[https://wiki.ubuntu.com/CrashReporting|crash report]] to Launchpad, a variety of files are attached, one of which is the CoreDump.gz file. Typically, after ARS processes this file, it removes it, and then the report [[https://wiki.ubuntu.com/Bugs/Status|Status]] or [[https://wiki.ubuntu.com/Bugs/Importance|Importance]] is changed, dependent on the outcome of how ARS processed the file. = ARS Messages = == outdated debug symbol package == An example ARS report comment: <

This might be caused by some outdated packages which were installed on your system at the time of the report: outdated debug symbol package for libfribidi0: package version 0.19.2-3 dbgsym version 0.19.2-1 Please upgrade your system to the latest package versions. If you still encounter the crash, please file a new report. Thank you for your understanding, and sorry for the inconvenience! }}} The package version the user has installed, 0.19.2-3, is newer than the one ARS has (0.19.2-1). This message could mean that the [[https://launchpad.net/ubuntu/+source/fribidi|libfribidi0]] package version 0.19.2-3 is unable to be processed by ARS because it cannot find the debug symbols for 0.19.2-3, it only has 0.19.2-1. In this case, this would not be something you did wrong or did not install, but a current limitation in ARS. == no debug symbol package found == Apport retracing service (apport) wrote on 2016-01-25: '''Crash report cannot be processed''' <

In this case, one would want to enable the [[https://wiki.ubuntu.com/Testing/EnableProposed|-Proposed]] repository, and if reproducible, file another crash report.
