Hi there,
I assume you are talking about the wallet and miner?

In all honesty, the easiest way to install on Ubuntu is through the bash script here
https://gist.github.com/anonymous/d1c1d35e3c8f67f5fb2e204479fa5c6b

1. Download that file and extract it somewhere on your machine.
2. Follow the instructions at that site (listed below)
2a) create an account and a worker name here (pool.biblepay.org)
2b) go to the downloaded directory (where you extracted that file)
2c) sudo chmod +x install_biblepay.sh
2d) ./install_biblepay.sh {number of mining threads} {pool worker name}
#    Eg: ./install_biblepay.sh 8 workername



EDIT: If you want to deploy the GUI after that, navigate in a terminal to the folder
$BP_ROOT/biblepay/src/qt

and type the command
./biblepay-qt

(you may need to restart the bbp service before this, I usually just restart my machine directly)
