Installations and Updates on Ubuntu are handled through the built in package
apt. All you need to do is add our code signing key, add our release
repository and install the app. The commands you need to run are listeed below.
wget -qO - https://gpmdp.xyz/bintray-public.key.asc | sudo apt-key add - echo "deb https://dl.bintray.com/marshallofsound/deb debian main" | sudo tee -a /etc/apt/sources.list.d/gpmdp.list sudo apt-get update sudo apt-get install google-play-music-desktop-player
When you want to update the player, simply run
sudo apt-get update && sudo apt-get upgrade
