A condensed variant of the Ubuntu Font Family was uploaded to the Private testing PPA yesterday.
The condensed font is provided in one weight, ‘regular’, and is provided without an†accompanying†italic.
The font is available to those subscribed to the ‘Ubuntu font private testing PPA‘ (which, despite the name, is available for anyone to subscribe to).
The font is not yet available at the ‘Ubuntu’ font listing on Google Web Fonts.
