Some time ago I told you that KDE will also have your own font call (like is logic) Oxygen, which we can already test.
A reader through a comment has passed me this link where we can download the typography to test it in different variants. We can download it in several ways through the terminal:
git clone git://anongit.kde.org/oxygen-fonts
Using Git with HTTP:
git clone http://anongit.kde.org/oxygen-fonts
Or Lowering the tarball:
wget -c http://anongit.kde.org/oxygen-fonts/oxygen-fonts-latest.tar.gz
With any of the 3 methods, we will obtain 3 folders which we can put inside / usr / share / fonts o ~ / .fonts. And ready..
