Source: rust-lalrpop Followup-For: Bug #995339 The d/copyright file is about the source package not the binary package, you are misinterpreting policy.
In fact there is nowhere in the d/copyright file format to put this information; and it would not be efficient to do so since the information already exists in the d/copyright of those other packages. Closing the bug report for this reason. -- System Information: Debian Release: bookworm/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-security'), (300, 'unstable'), (100, 'experimental'), (1, 'experimental-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-8-amd64 (SMP w/4 CPU threads) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
