Unfortunantly pkcon is very problamatic, and tries to install 64 bit packages on my 32 bit system with Multiarch
Maybe it's an issue that I enabled multiarch on my system, and never could get a 64 bit Kernel working with virtualbox, but this behaviour could cause problems on other peoples computers too...
