Introduction to the issue While trying to implement the kernel with the PREEMPT_RT patch, coming to the step : "$ make -j getconf _NPROCESSORS_ONLN deb-pkg"

The error : make[2]: *** [debian/rules:7: build-arch] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2 make[1]: *** [scripts/Makefile.package:77: deb-pkg] Error 2 make: *** [Makefile:1528: deb-pkg] Error 2

shows up and stop the building process of the kernel.

My currently kernel version is 5.11.0-40-generic. I chose the 5.11 and then the 5.10 and 5.4 kernel for the patch but the same error written few ligns up keeps showing up while building process.

~~Probably~~ Could be similar to https://github.com/frankaemika/libfranka/issues/62.

I was getting the same error. It worked after I followed Franka installation procedures and commented out these lines in .config CONFIG_SYSTEM_TRUSTED_KEY CONFIG_MODULE_SIG_KEY CONFIG_DEBUG_INFO_BTF
