I am running Ubuntu 10.04, Lucid Lynx, and I'm trying to add some fonts for use with Libre Office. In particular, I've placed a GillSans.ttc font file into /usr/share/fonts/truetype by copying it there with:

sudo cp GillSans.ttc /usr/share/fonts/truetype

and then attempting to "install" it by updating the font cache:

sudo fc-cache -fv

That appears to complete successfully, however, the font never seems to be available to either Libre Office, nor fontmatrix.

In addition, I tried adding the font to my .fonts directory, thinking that I was somehow seeing a cache of just user supplied fonts, but that isn't the case. The file is a .ttc file, is there some other tools I need to use to extract each font from the .ttc, or is there something else I must do to use a .ttc? Nothing appears to have any issue with the file, but it could be silently failing to do anything. I've looked for the answer in other places, but the only time that a similar question was asked, it did not appear to be answered, so I figured I would ask the question differently and see if anyone else might be able to clue me in on how to use a .ttc font file, if that is possible.

A related question, are there any tools to see what font families/font names are contained within a .ttc font file?
