Looks Neither is valid syntax. What you do with these is depending on a package with the literal architecture "same" (or "foreign"). Thats not going to work… > I was able to find documentation about what allowed is supposed to do, > but not on how to depend on such a package. > https://wiki.debian.org/Multiarch/HOWTO The spec [0] linked from that page says how, but in summary: If a package (lets say perl) is marked as Multi-Arch: allowed your package foo can depend on perl:any and a perl package from any (foreign) architecture will statisfy this dependency, while a 'simple' perl would have just accepted a perl from the architecture your package foo was built for (with arch:all mapped to arch:native). DO NOT use ":any" on a package which is NOT marked as Multi-Arch: allowed [1]. This isn't satisfiable by ANYTHING, not even your native package. If it helps: Instead of "perl having Multi-Arch: allowed" envision it to have a "perl provides perl:any" and you are depending on this virtual package – which also explains why such a missing provides causes perl:any to be unresolveable. That said, the usecase for 'allowed' is small – mostly interpreters – and you are trying to use it on… a -dbg package? I haven't looked closely, but that smells wrong… What are you trying to express here? (and have you heard that automatic debug packages are a thing nowadays?) Best regards David Kalnischkies [0] https://wiki.ubuntu.com/MultiarchSpec [1] There are ways around it. See the "If it helps" remark for a hint.
