In my opinion there is a bit of unclearity if this methode still works. Can anyone confirm if this guide will still work or if there is a link to a guide that does work on Ubuntu? And if it does not, how do you reverse the command: "sudo apt-get install git cmake g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev libboost-all-dev libssl-dev libncurses5-dev doxygen libreadline-dev dh-autoreconf"?
