fontspec throwing error with lualatex - broken?

Question

I get an error when I try to include the fontspec package. Here is a minimum working example:

\documentclass{article}
\usepackage{fontspec}
\begin{document}
Hello
\end{document}

I'm trying to compile this using the following build command: lualatex --file-line-error-style "%f". Part of the output that I get is:

/usr/share/texlive/texmf-dist/tex/latex/base/fontenc.sty:100: Font \EU2/lmr/m/n/

I would greatly appreciate any insight that you may have on this issue. I am using Linux Mint 16, with the standard texlive-luatex available in the repositories. Thank you.

Thanks for the prompt feedback!

Answer 1

I have just faced the same problem and it turns out that the solution was to install the lmodern package. If I understand correctly this also installs the fonts-lmodern package which contains the missing font file lmroman10-regular that lualatex was complaining about. (lmodern seems to contain font files for pdfTeX)

The conclusion is that this is perhaps not a TeX problem but rather a package dependency problem in the Linux Mint distribution (I am on Linux Mint Debian Edition). Still it seems a bit weird that lualatex requires a font that is not even used in the document.

Answer 2

You might be missing a required package, try:

sudo apt-get install texlive-luatex

Then, try the update:

luaotfload-tool --update
