! fontspec error: “font-not-found”

::

O sto dimenticando tutto o Debian Testing mi porta sfortuna…
Ho installato una serie di otf in /usr/local/texlive/texmf-local/fonts
quindi ho modificato /usr/local/texlive/2015/texmf-var/fonts/conf/texlive-fontconfig.conf
aggiungendo la riga
`

/usr/local/texlive/texmf-local/fonts`
Ho copiato il file modificato in
`/etc/fonts/conf.d/09-texlive.conf`
Ho lanciato `fc-cache -fsv`
e sembra che trovi i file dei font:

Ma se cerco di compilare con xelatex:

La procedura l’ho fatta varie volte, anche in questo caso
non riesco a individuare che cosa posso aver dimenticato…
