Well, that's the problem. The original Raspberry Pi A & B have an ARMv6 processor, whereas Debian's armhf port only supports ARMv7 and higher (e.g. the second and third editions of the Raspberry Pi). For this reason, Raspbian is a Debian derivative that recompiles all the armhf binaries for ARMv6+. But if one adds an official Debian repository (such as backports), then the code that is compiled will not work on ARMv6 processors. As far as I know, Raspbian doesn't provide a repository for backports, so one has three options, the way I see it: - don't use stuff from backports - compile the packages from jessie-backports for oneself on one's system, so they are compiled with the right build flags for one's machine - use the official Debian armel port instead of Raspbian The armel port is the port of Debian for ARM CPUs without hardware floating point support, and that has lower CPU requirements, so it will work on the RPi - but probably really, really slowly Anyway, this is not related to Debian or backports, because Debian does not support ARMv6 CPUs in the armhf port (it's mentioned in the release notes that armhf is for ARMv7 [1]), so binaries are not expected to work on ARMv6 CPUs. You could maybe also take it up with the Raspbian people to also add a backports repository to their derivative - but I wouldn't hold my breath there, because the newer models of the device are ARMv7 or even ARMv8, where even the official jessie-backports will work (at least when it comes to the supported instruction set, I have no idea if they will actually work or not).
