Debug BuildStream build failures by classifying the error category, such as source fetching or cache issues, then using specific `just` commands to inspect logs and element details to pinpoint the failing component.

Common BuildStream build errors include source fetching failures, build command errors, installation issues, composition problems, and cache issues. Identifying the correct category is the first step in the diagnostic flowchart to resolve pipeline errors.

Inspect logs for a failed BuildStream element by running specific `just` commands provided by the debugging guide. These commands allow you to view detailed error outputs and element details to understand why the build failed.

Yes, this debugging approach works for BuildStream cache proxy issues. It addresses CI-specific debugging scenarios and provides a diagnostic flowchart to help users efficiently resolve cache-related build pipeline errors.

The best way to troubleshoot BuildStream source fetching errors is to follow a systematic diagnostic flowchart. This involves categorizing the error as a source fetch issue and using specific `just` commands to inspect the element details and logs.
