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.
Actually, I think I spoke too soon... Armory's been sitting with no progress on Preparing Databases and Scan Transaction History progress indicators for over 12 hours!
That can't be right...does anyone know if this is a known issue? Thx!!
