Exaile is a music player similar with Amarok 1.4, written in Python.
Exaile handles well big libraries, fetches lyrics and album art, supports Last.FM. In this article I will show you how to install Exaile Music Player on Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin, via PPA:
$ sudo add-apt-repository ppa:exaile-devel/ppa
$ sudo apt-get update
$ sudo apt-get install exaile
I guess you have made a mistake in this line
sudo add-apt-repository:ppa:exaile-devel/ppa
It should be
sudo add-apt-repository ppa:exaile-devel/ppa
yes, you are right. I have fixed that issue 🙂
