Pull Request Overview
This pull request removes the dependency on fpm (Effing Package Manager) for creating DEB packages and instead implements native DEB package creation using dpkg-deb. The change aligns DEB packaging with the existing native approach used for RPM packages (via rpmbuild) and macOS packages (via pkgbuild/productbuild).
Key Changes:
- Implemented
New-NativeDebfunction to build DEB packages usingdpkg-debdirectly - Removed
fpmand its Ruby dependencies from bootstrap process - Removed the now-obsolete
Get-FpmArgumentsandInstall-GlobalGemfunctions - Added test coverage for DEB package naming validation
- Updated dependency checking to ensure
dpkg-debis available on relevant platforms

Impact
Tooling Impact
This change removes the dependency on fpm (Ruby gem) for DEB package generation and replaces it with the native dpkg-deb tool. This simplifies the build tooling requirements and reduces external dependencies.
Regression
This is not a regression but an improvement to the packaging process. It removes the fpm dependency for DEB package generation and uses native Linux tooling (dpkg-deb) instead.
Testing
The fix was verified through packaging tests that validate DEB package names and structure. The change was tested in the CI pipeline to ensure DEB packages are built correctly using dpkg-deb instead of fpm. Previous tests relied on fpm being installed, but now use dpkg-deb which is pre-installed on Debian-based systems and Mariner.
Risk
High risk because this changes the core packaging tooling for DEB packages. However, dpkg-deb is the native Debian packaging tool and is more reliable than fpm. The change has been tested in the main branch and reduces complexity by removing Ruby gem dependencies.
