    powerline-daemon -q

cd ~
cd ./src
git clone https://github.com/powerline/fonts.git --depth=1 powerline-fonts
cd powerline-fonts

# When it comes to choosing a font for powerline, I recommend firstly previewing them in an application called font-manager

sudo apt install font-manager
sudo vim /etc/vim/vimrc.local

set  rtp+=/usr/local/lib/python2.7/site-packages/powerline/bindings/vim/
set laststatus=2
set t_Co=256

In the Terminal app, select your font. Seem I like Noto Mono for Powerline Regular size 10

# powerline-config tmux setup

vim ./.tmux.conf 

source /usr/local/lib/python3.7/dist-packages/powerline/bindings/tmux/powerline.conf
set-option -g default-terminal "screen-256color"
