Issue details

Summary

Short introduction to the issue and how it impact you and why It is not possible to follow the mentioned steps here for ubuntu 22.04 with the standard Kernel 6.8.0 and this description https://docs.ros.org/en/ros2_packages/humble/api/ur_robot_driver/doc/installation/real_time.html

Issue details

Detailed description help us understand the problem. Code are welcome! There is no Kernel available for 6.8.0 and therefore I took the stabel LTS Version 5.15.179 https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git which I only can build with

make -j $(getconf _NPROCESSORS_ONLN) deb-pkg

The result is an Error dpkg-buildpackage: Information: Host-Architektur amd64 dpkg-source -i.git --before-build . debian/rules clean rm -rf debian/files debian/linux-* make clean dpkg-source -i.git -b . dpkg-source: Information: Quellformat »1.0« wird verwendet dpkg-source: Warnung: Quellverzeichnis »linux-5.15.179« lautet nicht <Quellpaket>-<Ursprungsversion> »linux-upstream-5.15.179-rt84« dpkg-source: Warnung: .orig-Verzeichnisname linux-5.15.179.orig ist nicht <Paket>-<Ursprungsversion> (linux-upstream-5.15.179-rt84.orig erwünscht) dpkg-source: Information: linux-upstream wird unter Benutzung des existierenden linux-upstream_5.15.179-rt84.orig.tar.gz gebaut dpkg-source: Information: linux-upstream wird in linux-upstream_5.15.179-rt84-1.diff.gz gebaut dpkg-source: Fehler: Änderung in vmlinux-gdb.py kann nicht dargestellt werden: dpkg-source: Fehler: neue Version ist Symlink auf /home/aut-laptop/rt_kernel_build/linux-5.15.179/scripts/gdb/vmlinux-gdb.py dpkg-source: Fehler: alte Version ist nicht existierend dpkg-source: Warnung: Löschen der Datei .scmversion wird ignoriert dpkg-source: Warnung: durch den Diff werden die folgenden Dateien der Originalautoren verändert: .clang-format .cocciconfig .get_maintainer.ignore .mailmap CREDITS MAINTAINERS README dpkg-source: Information: verwenden Sie das Format »3.0 (quilt)«, um separate und dokumentierte Änderungen an den Dateien der Originalautoren zu erhalten, siehe dpkg-source(1) dpkg-source: Fehler: nicht darstellbare Änderungen an der Quelle dpkg-buildpackage: Fehler: Unterprozess dpkg-source -i.git -b . lieferte Exitstatus 1 make[1]: *** [scripts/Makefile.package:77: deb-pkg] Fehler 1 make: *** [Makefile:1623: deb-pkg] Fehler 2

Steps to Reproduce
