I generally use Garamond as my default fonts in Latex writing. Partially because it is old-styled and still used in many French booklets.
If you don’t have Garamond fonts installed with your tex distribution, then following might be helpful for you.
download from CTAN, choose garamond zip file.
find your texmf tree in your file system, usually it is
install all .pfb files into
and all .afm files to
update fonts database by
sudo fc-cache -vf
delete the file
and configure by
sudo texhash then updmap --enable Map ugm.map
If everything is going correctly you will soon be able to use Garamond fonts. Good luck!
