Hi Samuel,Although I am not the maintainer of this package, from what I can see librust-version-ranges-dev is an actual dependency of pep440-rs [1], which has been stuck in the NEW queue for more than two weeks now [2].
Cheers [1] https://github.com/konstin/pep440-rs/blob/main/Cargo.toml [2] https://ftp-master.debian.org/new/rust-version-ranges_0.1.0-1.html
