An arch:all package by default is considered to be of the same
architecture as the native one. So yelp:amd64 depending on python3-distro
implies it wants python3-distro:amd64 which is not satisfied as it is
only evaluated as python3-distro:i386.
To tell the packaging system that this dependency is safe and truly
architecture independent, it needs to be marked as Multi-Arch: foreign.
