I'm trying to write a tutorial for people without internet-enabled Pis on how to install Debian packages manually.
I'm checking the dependencies for the packages to see what is required, manually downloading the required .deb files, copying them over to the Pi and then installing them in reverse order using dkpg.
The thing is, I've tried two packages now (reasonably complex to show how to resolve dependencies) and both fail. Both packages work if installed using apt-get (which defeats the purpose). I have also checked the manually installed packages with apt-rdepends and everything seems fine, only they don't work (illegal instruction).
Am I doing something wrong, or is something missing (note: I'm pretty certain I'm not missing a package)?
