launchpadlib is an officially supported Python library for scripting Launchpad.net through its web services interfaces. It allows interaction with Launchpad objects like bugs, blueprints, and packages. The current version is 2.1.0, and it generally follows an as-needed release cadence for bug fixes and Python compatibility updates.

This quickstart demonstrates both anonymous and authenticated access to the Launchpad API. Anonymous access is suitable for reading public data. Authenticated access (via `login_with_creds`) allows for private data access and write operations, often requiring interactive credential setup or pre-existing credential files for automated scripts. Remember to use a unique application name.
Upgrade to Python 3.8+ and install launchpadlib 2.x. If you have legacy Python 2 code, it will require porting.
Ensure your system's CA certificates are up-to-date. In some cases, configuring `HTTP_PROXY` or `HTTPS_PROXY` environmental variables incorrectly can also lead to issues. If strictly necessary and aware of security implications, you might temporarily disable verification (e.g., `httplib2.Http(disable_ssl_certificate_validation=True)`), but this is not recommended for production.
For automated scripts, ensure credentials are pre-cached by running the script once interactively, or explicitly provide a `credentials_file` argument to `login_with_creds` pointing to a file with pre-obtained credentials (e.g., `~/.launchpadlib/creds`). Ensure your application name is consistent.
Implement exponential backoff and retry logic for your API calls. Design your scripts to make efficient use of the API, fetching data in batches where possible rather than individual items.
Ensure launchpadlib is installed in your active Python environment: `pip install launchpadlib`.
Use `Launchpad.login_with_creds()` and ensure you have valid, cached credentials. If running interactively, it should prompt you. For scripts, verify `~/.launchpadlib/creds` exists and is valid, or explicitly provide a `credentials_file`.
Update your operating system's CA certificates. If behind a corporate proxy, consult your IT department for proper proxy configuration (e.g., `HTTP_PROXY`, `HTTPS_PROXY` env vars) or necessary custom certificate installations.
Double-check the identifier or URL you are using. For example, ensure the person's Launchpad ID or project name is spelled correctly.
