Testing with Ubuntu 20

Instructions for installing 3.8.1.0-rc1 and the latest Ubuntu 20 daily build:

• Download latest daily build of Ubuntu 20 - http://cdimage.ubuntu.com/daily-live/current/focal-desktop-amd64.iso
• Install it on a VM or wherever (I recommend 15 GB)
• Side note- I was stuck in a login-loop until I chose "Wayland" using the little button that shows up after you click your login name
• Open Ubuntu's "Software & Updates" screen > Developer Options tab > Check the box "Pre-released Updates"
• sudo apt-get update
• sudo apt install git cmake g++ libboost-all-dev libgmp-dev swig python3-numpy python3-mako python3-sphinx python3-lxml doxygen libfftw3-dev libsdl1.2-dev libgsl-dev libqwt-qt5-dev libqt5opengl5-dev python3-pyqt5 liblog4cpp5-dev libzmq3-dev python3-yaml python3-click python3-click-plugins python3-zmq python3-scipy
• sudo apt-get install gnuradio
• Make sure it installed 3.8.1
