There are a few applications available for listening internet radio stations in Ubuntu Desktop. Gradio is new one that allows users to find radio stations by typing a keyword in the search box, and then listen to one internet radio by clicking on it.
The simple tool requires GTK3 >= 3.18, so it works on Ubuntu 16.04, Ubuntu 16.10, and their derivatives, e.g., Linux Mint 18 and Elementary OS 0.4 Loki.
How to install Gradio in Ubuntu 16.04:
The pre-compiled binary packages are available for download at the link below:
Choose amd64.deb for 64-bit system and i386.deb for 32-bit system, and then click install the package via Ubuntu Software.
For those who want to add the PPA and receive future updates via Software Updater, open terminal (Ctrl+Alt+T) and run commands to add the PPA repository (so far supports for Ubuntu 16.04 and 16.10):
sudo add-apt-repository ppa:haecker-felix/gradio-daily sudo apt update sudo apt install gradio
(Optional) To remove the software, simply run
apt command with
sudo apt remove gradio
And the PPA can be remove by launching Software & Updates utility and navigating to Other Software tab.
