No clear sense. I just wonder that will conficts happen for native gcc:i686 conflict with gcc-i686-linux-gnu:amd64? if gcc-i686-linux-gnu:amd64 is marked as Multi-Arch:foreign. And how about if multi foreign architecutures are added, for example: i686> dpkg --add-architecutre amd64 arm64 ppc64el ? > > Helmut -- YunQiang Su
