Here was my solution to get it running at all:
cd Downloads/SoundJackLinux/
export LD_LIBRARY_PATH=/home/ubuntu-studio/Downloads/SoundjackLinux:$LD_LIBRARY_PATH
sudo add-apt-repository ppa:linuxuprising/libpng12
sudo apt update
sudo apt install libpng12-0
wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb
sudo dpkg -i libicu55_55.1-7_amd64.deb
sudo apt-get install libpcre16-3
then reboot
