Ubuntu Bug Reporting

Introduction

Bug reporting is an essential part of the open-source ecosystem and a valuable way to contribute to the Ubuntu community. When you encounter an issue or unexpected behavior in Ubuntu, reporting it properly helps developers identify, understand, and fix problems. This guide will walk you through the process of effective bug reporting in Ubuntu, from identifying bugs to submitting well-documented reports that lead to solutions.

What is a Bug?

In software terms, a bug is any unexpected behavior, error, or flaw in a program that causes it to produce incorrect results, behave in unintended ways, or crash. Bugs can range from minor inconveniences to critical issues that prevent system functionality.

A bug in Ubuntu might be:

• An application that crashes unexpectedly
• A feature that doesn't work as documented
• A graphical glitch in the user interface
• Hardware that isn't recognized correctly
• Performance issues under specific conditions

Why Report Bugs?

Before diving into how to report bugs, let's understand why it matters:

1. Community Improvement: Your reports help make Ubuntu better for everyone
2. Developer Awareness: Developers can't fix what they don't know about
3. Personal Growth: You'll learn more about how Ubuntu works
4. Recognition: Become a valued contributor to the Ubuntu ecosystem

Prerequisites for Bug Reporting

Before reporting a bug, make sure you have:

• An Ubuntu One account (for Launchpad access)
• A basic understanding of the issue you're experiencing
• Time to provide detailed information and follow up if needed

The Bug Reporting Process

Let's walk through the complete process of reporting a bug in Ubuntu:

1. Identifying a Bug

First, you need to determine if what you're experiencing is actually a bug:

• Is the behavior inconsistent with what's documented?
• Does it happen consistently or only under certain conditions?
• Does it affect system functionality or user experience?

2. Collecting Information

Before reporting a bug, gather essential information about your system:

Using the ubuntu-bug Tool

The ubuntu-bug command is your primary tool for reporting bugs. It automatically collects relevant system information:

bash

ubuntu-bug package-name

Replace package-name with the name of the package that contains the bug. For example:

bash

ubuntu-bug firefox

If you don't know the package name, you can use:

bash

ubuntu-bug

And follow the prompts to identify the affected application or component.

Manual Information Collection

If needed, you can manually collect information:

• Ubuntu version:

bash

lsb_release -a

• Kernel version:

bash

uname -a

• Hardware information:

bash

sudo lshw > hardware-info.txt

• Package version information:

bash

apt show package-name

• Application-specific logs (often found in /var/log/ or ~/.config/)

3. Checking for Existing Bug Reports

Before submitting a new bug report, check if someone has already reported the issue:

1. Visit Launchpad
2. Use the search function with keywords related to your issue
3. Browse through related packages or projects

If you find an existing bug that matches your issue:

• Add a comment with any new information
• Click "This bug affects me too" to subscribe to updates
• Add any unique details about your specific situation

4. Submitting a New Bug Report

If your issue hasn't been reported yet, follow these steps to create a new bug report:

Using ubuntu-bug (Recommended Method)

1. Open Terminal
2. Run the ubuntu-bug command for the affected package:

bash

ubuntu-bug firefox

3. This will gather system information and open a browser window to Launchpad
4. Log in with your Ubuntu One account
5. Complete the bug report form

Direct Submission on Launchpad

If you can't use ubuntu-bug, you can submit directly on Launchpad:

1. Go to https://bugs.launchpad.net/ubuntu/+filebug
2. Click "No, I need to report a new bug"
3. Fill in the required information

5. Writing an Effective Bug Report

A good bug report contains:

Clear Title Create a descriptive, specific title that summarizes the issue:

• ❌ "Firefox doesn't work"
• ✅ "Firefox 123.0 crashes when opening PDF attachments on Ubuntu 24.04"

Detailed Description Include:

• What happened
• What you expected to happen
• Step-by-step reproduction instructions
• System information
• Error messages (exact text)
• Screenshots (if visual issues)

Example Bug Report Template

## What happened
When opening PDF attachments in Firefox 123.0, the browser crashes immediately.

## Steps to reproduce
1. Open Firefox
2. Go to my Gmail account
3. Open any email with a PDF attachment
4. Click on the PDF attachment
Result: Firefox closes unexpectedly

## Expected behavior
The PDF should open in Firefox's built-in PDF viewer.

## Frequency
Happens 10/10 times when attempting to open any PDF attachment.

## Additional information
- This started happening after the latest Firefox update
- I can open PDFs from local files without issues
- I've tried disabling all extensions

6. After Submitting a Bug Report

Your responsibility doesn't end with submitting the report:

1. Monitor the report for questions or requests for additional information
2. Respond promptly to developer inquiries
3. Test proposed fixes when they become available
4. Update the report with new information as you discover it

7. Understanding Bug Status and Priority

Bug reports go through several stages:

• New: Just reported, not yet confirmed
• Confirmed: Verified as a legitimate bug
• Triaged: Assessed and prioritized
• In Progress: Developers are working on it
• Fix Committed: Fix has been developed but not released
• Fix Released: Fix is available in a released update

Priorities range from "Critical" (system crashes, data loss) to "Wishlist" (feature requests).

Practical Example: Reporting a Bluetooth Connection Issue

Let's walk through reporting a bug where Bluetooth headphones disconnect randomly:

1. Identify the issue: Bluetooth headphones disconnect every 5 minutes despite being fully charged.

2. Collect information:

   bash

   ubuntu-bug bluetooth

3. Check for existing reports: Search Launchpad for "bluetooth disconnect headphones"

4. Submit a report using information like:

   ## What happened
   My Sony WH-1000XM4 Bluetooth headphones disconnect approximately every 5 minutes when connected to my Ubuntu 24.04 laptop.
   
   ## Steps to reproduce
   1. Pair Sony WH-1000XM4 headphones with Ubuntu laptop
   2. Play audio (music, video, or conference call)
   3. Wait approximately 5 minutes
   Result: Headphones disconnect, audio switches to laptop speakers
   
   ## Expected behavior
   Headphones should maintain a stable connection until manually disconnected or powered off.
   
   ## Frequency
   Happens consistently every 4-6 minutes.
   
   ## Troubleshooting already attempted
   - Headphones work fine with my Android phone
   - Tried removing and re-pairing the device
   - Tested with a different pair of Bluetooth headphones (similar issue)
   - Updated to the latest system updates
   
   ## System information
   Ubuntu 24.04 LTS
   Kernel: 6.5.0-15-generic
   Bluetooth controller: Intel AX200

5. Follow up: Respond to any questions from the developers and test proposed fixes.

sudo btmon > bluetooth-log.txt

Use Apport to collect crash information

bash

sudo systemctl enable apport
sudo systemctl start apport

Run applications in debug mode

bash

WEBKIT_DEBUG=1 firefox

Contributing to Bug Fixes

If you have programming skills, you might even contribute patches:

1. Download the source code:

   bash

   apt source package-name

2. Make your changes

3. Create a patch:

   bash

   diff -u original-file modified-file > fix.patch

4. Attach the patch to the bug report
