Package: why Version: 2.18.dfsg-4+b1 Severity: important why uses ${binary:Version} to indicate why-examples's required version of why and why's suggested version of libwhy-coq. However, that variable is only appropriate for relationships between architecture-dependent packages; because why-examples and why-coq are both architecture-independent, binary-only rebuilds (as recently occurred for the ocaml 3.11.1 transition) render them unsatisfiable.
For why-examples -> why, you could change the dependency to something like why (>= ${source:Version}), why (<< ${source:Version}.1) to allow for rebuilds but not more substantial changes. Any-to-all relationships are easier to handle, so why could simply change its suggestion to libwhy-coq (= ${source:Version}). However, given that libwhy-coq, even if technically architecture-independent, is relatively small and itself in need of rebuilds for various transitions, it might actually make some sense to keep the relationship as is and set libwhy-coq's architecture to any. (For instance, it's uninstallable at present due to a dependency on coq-8.2-1+3.11.0.) -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.30-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages why depends on: ii libatk1.0-0 1.26.0-1 The ATK accessibility toolkit ii libc6 2.9-19 GNU C Library: Shared libraries ii libcairo2 1.8.8-2 The Cairo 2D vector graphics libra ii libfontconfig1 2.6.0-4 generic font configuration library ii libfreetype6 2.3.9-5 FreeType 2 font engine, shared lib ii libglib2.0-0 2.20.4-1 The GLib library of C routines ii libgtk2.0-0 2.16.4-1 The GTK+ graphical user interface ii libpango1.0-0 1.24.3-1 Layout and rendering of internatio Versions of packages why recommends: ii alt-ergo 0.9-1 Automatic theorem prover dedicated Versions of packages why suggests: pn libwhy-coq <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
