Install Mac & Win Fonts on Ubuntu

Installing TrueType fonts is very easy on Ubuntu. On your desktop or in a file-browser window, just type Ctrl-L to access the Open Location window; then type fonts:/// and click Open. You will then see a list of all the fonts you currently have access to on your system. Drag your new TrueType font from your desktop or file manager into the font-list window, and it will be automatically installed and made available to applications through Defoma the next time they start up.

It's actually not quite that simple if the fonts come from a Macintosh system, because Mac OS embeds extra font information using a special format that Linux can't read directly. Before you drag Mac OS fonts into your fonts:/// folder, you need to convert them with a utility called fondu, which you can install with the following command:

sudo apt-get install fondu

Then copy your Mac OS font directory to your Linux machine and run:

fondu *
