Package: libguestfs0 Version: 1:1.42.0-6 Severity: minor sgabios these days is provided by qemu-system-data package, which is a dependency of qemu-system-x86 which is a required package for libguestfs. There's no need for libguestfs0 to depend on sgabios separately.
Setting severity to `minor' because explicit dependency does not really hurt, it gets satisfied by qemu-system-data anyway. But it'd be nice to tidy this up. The talk is about the sid/testing version, since in buster the dependency is actually needed in this case, in buster sgabios was entirely optional while in next release it is an integral part of qemu and is always available with qemu-system-x86.
