This commit implements a complete parallel repository management system
that allows building and publishing Debian repositories in parallel,
significantly reducing build time for multiple distributions.
- `update-main`: Builds common/main component once for all releases
- `update -R <release>`: Builds release-specific components in isolated DBs
- `merge`: Combines common + release-specific components into final repos
- Isolated databases (aptly-isolated-<release>) avoid locking during parallel builds
- Common component built once, not duplicated per release
- Release-specific components (utils, desktop) built independently
- Final merge combines all components with proper GPG signing
- Fixed GPG signing to target top-level Release files (dists/{release}/Release)
- Pool cleanup before publishing avoids "file already exists" errors
- Smart package import skips duplicates during merge
- Proper handling of empty repositories and missing components
- Improved error handling and logging throughout
1. update-main: Build common component (once)
2. update -R <release>: Parallel workers build release-specific components
3. merge: Combine all components and publish with GPG signatures
This enables GitHub Actions to run multiple release builders in parallel,
reducing total repository build time from hours to minutes.

Purpose of This Repository
The Armbian Linux Build Framework creates customizable OS images based on Debian or Ubuntu for single-board computers (SBCs) and embedded devices.
It builds a complete Linux system including kernel, bootloader, and root filesystem, giving you control over versions, configuration, firmware, device trees, and system optimizations.
The framework supports native, cross, and containerized builds for multiple architectures (x86_64, aarch64, armhf, riscv64) and is suitable for development, testing, production, or automation.
Looking for prebuilt images? Use Armbian Imager — the easiest way to download and flash Armbian to your SD card or USB drive. Available for Linux, macOS, and Windows.
Quick Start
