Fonts missing

[Sylvia Sánchez]

Hello everybody!  Happy new year!

I've just installed the Spherical Cow and I can use my older
fonts.  I used to copy&paste from one /usr/share/fonts folder to the
other but this time it isn't working.
My fonts are in Ubuntu, as root I copy & paste from there to my new
Fedora.  But I can't use them anyway.
Somebody know why it happens and how can I fix it?

Thank you all very much!
Lailah
