[Tex/LaTex] xelatex does not find Fira Sans using metropolis theme (beamer)

beamerfontsxetex

I am using beamer with metropolis to make a presentation. I installed the Fira font family and everything seems to work (I can use it in other programs). However, everytime I try to compile my presentation, xelatex aborts with the error message:

xdvipdfmx:fatal: Cannot proceed without the font: /usr/share/fonts/truetype/FiraSans/Normal/Roman/FiraSans-Regular.woff

The font exists at this path and it is listed by fc-list, so it seems very cryptic to me. I think it is something specific to my texLive installation or the way I installed the Fira fonts, since it compiles on Windows (I am using Ubuntu). There is nothing special about the presentation, the following MWE reproduces this error:

\documentclass[]{beamer}

\usetheme[numbering=none,sectionpage=none,subsectionpage=none,block=fill]{metropolis}

\setsansfont[BoldFont={Fira Sans}]{Fira Sans Light}
\setmonofont{Fira Mono}

\title{This is the title}
\subtitle{with subtitle}
\date{Feb 2018}
\author{author}

\begin{document}

\begin{frame}[fragile]
    \frametitle{the title}
    \begin{center}
        This is the text
    \end{center}
\end{frame}

\end{document}

Does anyone have any idea?

Best Answer

I am posting the answer here but it is mostly answered from How to set up the font Scheherazade for use with XeLaTeX?

I simply replaced

\setsansfont[BoldFont={Fira Sans}]{Fira Sans Light}
\setmonofont{Fira Mono}

by 

\setsansfont[BoldFont={FiraSans-Bold.ttf}]{FiraSans-Light.ttf}
\setmonofont{FiraMono-Regular.ttf}

to force xelatex to use those fonts instead of whatever it finds in the path that matches the name I provide.

Thanks to both samcarter and Ulrike Fischer for the help!
