Before you go any further guessing that your N9 is 059L7N7: N9 RM-696 Country Variant Sweden SE Magenta_COLOR which may be the problem as N9Repomirror can have problems with some regional variants rather than devices running global, although should have been resolved in version 0.7.2
Only try to install n9repomirror_0.7.2_armel.deb
