Commands I've tried:
sudo fc-cache -fv
Dispite this I was unable to make Monofur font to display as available for the Gnome Terminal in a machine with Ubuntu 14.10 recently installed. It's available in all other apps.
I have other machine with 14.04 where this went fine.
I'm not sure whether this is related with a problem when I installed the font for the first time and the font manager got stuck when installing that I had to reboot. Afterwards I've removed the font from the system and reinstalled it without problems.
fc-list lists this font. File permissions are OK.
Upgraded to last Ubuntu, issue vanished.
