If you want to add information on how to debug a package to this page, 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 ubuntu-bugsquad@lists.ubuntu.com . Or in #ubuntu-bugs on irc.ubuntu.com .
