A Little guide to build Armory from source on a clean Ubuntu system:
sudo apt-get update && apt-get upgrade -y
sudo apt-get install git autoconf libtool libqt4-dev libqtcore4 pyqt4-dev-tools swig g++ python-dev python-psutil libqtcore4 libqtcore4 pkg-config -y
git clone https://github.com/goatpig/BitcoinArmory.git
cd BitcoinArmory/
git checkout testing
git submodule init
git submodule update
./autogen.sh
./configure
make -j$(grep -c ^processor /proc/cpuinfo)
make install
#Install Bitcoind ( In this example core but will work with BU/Classic and probably many other nodes also )
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sud apt-get install bitcoind
#Run Bitcoind:
bitcoind -daemon
#Now wait till Bitcoind is synced and start Armory.
