In brief, the problem I seem to be having is that apt-get "ignores" whatever PPA I add. I assume that this is because the respective PPA's limit their debs to i386 and AMD64 builds. (I'm using armhf.) This causes a problem though. I'd like to use "apt-get source -b" to build the respective debs. However, even when enabling the PPA's deb-src repository, apt-cache policy still doesn't "find" the respective packages. I'm forced to download the packages, configure/make/checkinstall.
Am I correct in thinking I should be able to compile these packages on arm via "apt-get source -b"? If so, how do I force ubuntu to load these repositories? That is, how do I stop apt-get from "IGN"oring these PPAs?
