Don't forget to run "fc-cache -fv" or "sudo fc-cache -fv" (if not running as
su) in terminal after you copy over the fonts to update the font cache and
make the fonts permanent.
As stated earlier, the typical font folders are in /usr/share/fonts or the
./fonts directory (hidden in your HOME directory) that the system will use.
The /usr/share/fonts folder has both opentype and truetype folders that the
installers install into. Even when I am manually adding fonts, I tend to
respect those folders.
There are a couple of libre fonts that aren't in the Trisquel 6 repos like
http://packages.ubuntu.com/quantal/fonts-lato and
http://packages.ubuntu.com/raring/fonts-roboto that were added in newer
Ubuntu releases. The nice thing about these fonts is that they are singular
.deb files that can be easily installed with Gdebi.
