Hello,
The OP already mentioned that this file is present in his installation, so it is unclear why it wasn't found.hille@sid:~ $ apt-file search fourier-orns.sty texlive-fonts-extra: /usr/share/texlive/texmf-dist/tex/latex/fourier/fourier-orns.sty
The file *is* found. In the original message I posted LaTeX's error: [...] (/usr/share/texlive/texmf-dist/tex/latex/fourier/fourier-orns.sty kpathsea: Running mktextfm FourierOrns /usr/share/texlive/texmf-dist/web2c/mktexnam: Could not map source abbreviation F for FourierOrns. /usr/share/texlive/texmf-dist/web2c/mktexnam: Need to update /usr/share/texlive/texmf-dist/fonts/map/fontname/special.map?mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode;

I can't find file `FourierOrns'. <*> ...our; mag:=1; nonstopmode; input FourierOrns [...] So there seems to be a missing file, but not fourier-orns.sty . Kind regards, Sébastien.
