Any ideas? Can't access my bitcoin since segwit. 
You are missing several build steps. Follow the instructions at https://btcarmory.com/docs/building/Thanks mate, that did it.
(My problem was that I was following the build steps at https://github.com/goatpig/BitcoinArmory/blob/master/linuxbuild/Linux_build_notes.md which seem to be missing pretty much all those other steps...)
It's up and running now.
