Many thanks! I've run a number of tests covering different options (native/foreign chroot, implicit/explicit mirror, plain-url/sources.list-entry, mirror information via stdin/on the commandline, target directory/tarball) with the current upstream git head and everything looks good: * native chroot with default mirror and with a directory as the target: # mmdebstrap --include="debian-ports-archive-keyring" sid /tmp/amd64-chroot I: chroot architecture amd64 is equal to the host's architecture I: automatically chosen mode: root I: running apt-get update... done I: downloading packages with apt... done I: extracting archives... done I: installing packages... done I: downloading apt... done I: installing apt... done I: installing remaining packages inside the chroot... done I: cleaning package lists and apt cache... done done * native chroot with a mirror URL on the commandline and a directory as the target: # mmdebstrap --include="debian-ports-archive-keyring" sid /tmp/amd64-chroot http://deb.debian.org/debian I: chroot architecture amd64 is equal to the host's architecture I: automatically chosen mode: root I: running apt-get update... done I: downloading packages with apt... done I: extracting archives... done I: installing packages... done I: downloading apt... done I: installing apt... done I: installing remaining packages inside the chroot... done I: cleaning package lists and apt cache... done done * foreign (riscv64) chroot with sources.list passed on stdin and with a directory as the target: # echo -e "deb http://deb.debian.org/debian-ports/ sid main\ndeb http://deb.debian.org/debian-ports/ unreleased main" | mmdebstrap --architectures=riscv64 --include="debian-ports-archive-keyring" sid /tmp/rv64-chroot I: riscv64 cannot be executed, falling back to qemu-user I: Reading sources.list from standard input...
