[Tex/LaTex] Problem with stix fonts in texlive 2018

I have been using stix fonts with texlive 2017. Now I am getting weird error messages. Here is a minimum working example:

\documentclass{book}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{stix}
\begin{document}
    \(\cos^2\theta+\sin^2\theta=1\)
\end{document}

I am reproducing an edited version of the log since it is too long.

I get the following error message right at begin document.
! LaTeX Error: This NFSS system isn't set up properly.“
Can it because the texlive 2018 installation is corrupted?

Best Answer

When the stix package was updated on TeX Live, the necessary font description .fd files were dropped, I assume by mistake as even a new .fdd file was added (separate source for the .fd files).

Temporary solution until the situation is fixed: copy the stix.fdd file in the working directory

cp /usr/local/texlive/2018/texmf-dist/source/fonts/stix/stix.fdd .

and run tex on it

tex stix.fdd

This will generate the necessary .fd files and LaTeX should be happy to run your old documents.

If you don't have stix.fdd on your system, you can directly download it from CTAN: http://mirrors.ctan.org/fonts/stix/latex/stix.fdd

Use stix2 for newer ones.

UPDATE

Revision 47652 of the package on TeX Live has fixed the problem
