Package: ftp.debian.org
https://metadata.ftp-master.debian.org/changelogs/main/libx/libxcrypt/unstable_copyright
is from 2016, even though this package had the last upload on
2022-11-02.
Aha, it's probably because the source package doesn't ship
debian/copyright; instead, it generates it at build time:
$ cd libxcrypt-4.4.30/
$ ls debian/copyright*
debian/copyright.in
$ grep -w copyright debian/rules | tail -n1
cat debian/copyright.in LICENSING > debian/copyright
Eww.
Anyway, if an up-to-date copyright file is not available, I'd prefer to
get 404 rather than an obsolete one.
