I'm seeing a fun issue with Ubuntu 24.04 (Noble)... 13.14.1ubuntu5:
https://launchpad.net/ubuntu/+source/debhelper

dpkg-buildpackage --build=binary --no-pre-clean --unsigned-changes
-R'make -f debian/rules' -j1 -a$(cat debian/arch)
dpkg-buildpackage: info: source package linux-upstream
dpkg-buildpackage: info: source version 1noble
dpkg-buildpackage: info: source distribution noble
dpkg-buildpackage: info: source changed by rcn-ee <robertcnelson@xxxxxxxxx>
 dpkg-source --before-build .
dpkg-buildpackage: info: host architecture armhf
dpkg-checkbuilddeps: error: Unmet build dependencies: debhelper-compat (= 12)
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

Where as Debian (testing) Trixie and Sid: 13.15.3
https://packages.debian.org/source/trixie/debhelper

dpkg-buildpackage --build=binary --no-pre-clean --unsigned-changes
-R'make -f debian/rules' -j1 -a$(cat debian/arch)

Not really sure why Noble is failing, but wonder if, would fix it..
Build-Depends: debhelper-compat (>= 12)
