Report bugs in Ubuntu
As of 10.04 LTS, you need to use this command-line to reports bugs to the launchpad.net tracking system (you need a launchpad acct for this to work). This command is preferred over using the website because it collects/sends info about your system to help developers. ubuntu-bug is a symlink to apport-bug which sees if KDE/Gnome is running and calls apport-gtk/apport-kde dialogs, otherwise apport-cli, so you can fill out a bug report. First run 'ubuntu-bug' without args to see a list of known symptoms. If there's no matching symptom, or you know which package is to blame, then run 'ubuntu-bug <package>'. If the process is still running, use 'ubuntu-bug <PID>'
