this should fix it: https://salsa.debian.org/debian/sbuild/-/merge_requests/106 It solves the problem by installing apt-utils:native into the chroot when cross building. I'd like to avoid installing more packages into a build-chroot that I would like to have as minimal as possible. But I don't see another way to properly fix it. Does anybody else have another idea? Thanks! cheers, josch
