If you want to add information to this page on how to debug a package, use this template.
As part of triaging bug reports about specific packages or subsystems, bug triagers and developers have been writing debugging procedures for them. These include information about how to troubleshoot issues, gather the proper log files and common bug reports. If you find one missing, and if no one else can help, e-mail the Bug Squad! You can find them at firstname.lastname@example.org . Or in #ubuntu-bugs on irc.ubuntu.com .

We've created a template file for debugging procedure pages if you want to write a new one. The template provides a similar look and feel for all pages and ensures that they cover common subjects.
