Interact with Canonical's Launchpad platform via the Launchpad API (api.launchpad.net) using the lp-api CLI tool. Use when working with Ubuntu/Debian packages, bugs, builds, people, projects, or any Launchpad API resources. Triggered by mentions of Launchpad API, Ubuntu development, package builds, or bug tracking.

Launchpad API

Overview

This skill enables interaction with Canonical's Launchpad platform (https://launchpad.net) through direct API calls using the lp-api command-line tool. It provides full CRUD capabilities (Create, Read, Update, Delete) for querying and managing bugs, people, projects, builds, and other Launchpad resources via the official API at https://api.launchpad.net/devel.html.

API-First Approach: This skill focuses on direct API interaction using lp-api, not the web UI or Python launchpadlib. All operations are performed via HTTP requests to api.launchpad.net.

Important Note: All lp-api commands return JSON responses except using with ws.show==total_size, or using download and pipe subcommands. Parse these outputs to extract meaningful information.

Installation & Troubleshooting

If lp-api is not found, use the GitHub API to find and download the correct binary for your system.

1. Find download URL:

# Get the browser_download_url for your OS (linux/darwin/windows) and Architecture (amd64/arm64)
# Example for Linux AMD64:
curl -s https://api.github.com/repos/fourdollars/lp-api/releases | \
  jq -r '.[0].assets[] | select(.name | endswith("linux-amd64.tar.gz")) | .browser_download_url'

2. Download and Install:

curl -L -o lp-api.tar.gz <URL>
tar -xzf lp-api.tar.gz
chmod +x lp-api
mkdir -p bin
mv lp-api bin/
export PATH=$PWD/bin:$PATH

Authentication

The tool handles OAuth authentication automatically:

  1. Environment Variable (preferred for CI/CD):

    export LAUNCHPAD_TOKEN="oauth_token:oauth_secret:consumer_key"

  2. Config File (for interactive use):

    • Stored at .lp-api.toml in the current directory (recommended)
    • Use -conf .lp-api.toml to specify the location
    • Created automatically on first run via OAuth flow
    • User prompted to authorize at launchpad.net

Quick Tips

Search Bugs Across ALL Projects

To find bugs you're involved with across all projects and distributions, use searchTasks on the person resource:

# Get your person link
ME_LINK=$(lp-api get people/+me | jq -r '.self_link')

# All bugs assigned to you (across all projects)
lp-api get people/+me ws.op==searchTasks assignee==$ME_LINK

# Filter by status
lp-api get people/+me ws.op==searchTasks assignee==$ME_LINK status=="In Progress"

# Bugs you reported, subscribed to, or have activity on
lp-api get people/+me ws.op==searchTasks bug_reporter==$ME_LINK
lp-api get people/+me ws.op==searchTasks bug_subscriber==$ME_LINK
lp-api get people/+me ws.op==searchTasks bug_commenter==$ME_LINK  # includes any activity
lp-api get people/+me ws.op==searchTasks affected_user==$ME_LINK

Note: bug_commenter includes any bug activity (comments, status changes, field updates), not just message comments.

This is equivalent to the web UI at https://launchpad.net/~username/+assignedbugs.
