Running on an arm64 build machine, I checked out from git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal the branch HEAD detached at Ubuntu-5.4.0-39.43 and follow the instructions at https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel#Modifying_the_configuration and find that it iterates through all target machines, and requires that each target's cross compiler to be installed correctly.
So from my perspective, working as close as possible to head, I still see the same problems I don't know why this was marked 'invalid'. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1863116 Title: debian/rules editconfigs does not work on s390x to change s390x only configs Status in Ubuntu on IBM z Systems: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: On s390x pull-lp-source linux-5.4 cd linux-* fakeroot ./debian/rules clean ./debian/rules editconfig dh_testdir; /bin/bash -e debian/scripts/misc/kernelconfig editconfigs Do you want to edit config: amd64/config.flavour.generic?

Only s390x ones. As a user, I should be able to rebuild ports architecture kernel with tweaked config for testing, self-hosted without cross-compilers.
