Hello,
hille@sid:~ $ apt-file search fourier-orns.sty
texlive-fonts-extra:
/usr/share/texlive/texmf-dist/tex/latex/fourier/fourier-orns.sty
The OP already mentioned that this file is present in his installation,
so it is unclear why it wasn't found.
The file *is* found.
In the original message I posted LaTeX's error:
[...]

F for FourierOrns.

This is METAFONT, Version 2.7182818 (TeX Live 2019/Debian) (preloaded
base=mf)
kpathsea: Running mktexmf FourierOrns

So there seems to be a missing file, but not fourier-orns.sty .
Kind regards,
Sébastien.
