TeXLive: LaTeX document using newtxtext package fails compilation

[romildo]

Compilation of LaTeX documents using the newtxtext LaTeX package fails because of font issues.

For instance, the LaTeX document test.tex below does not compile.

\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{newtxtext}

\begin{document}

Hello, world!

\end{document}

$ pdflatex test
[...]

kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 ntx-Regular-tlf-t1
mktexpk: don't know how to create bitmap font for ntx-Regular-tlf-t1.
mktexpk: perhaps ntx-Regular-tlf-t1 is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.

!pdfTeX error: /run/current-system/sw/bin/pdflatex (file ntx-Regular-tlf-t1): F
ont ntx-Regular-tlf-t1 at 600 not found
 ==> Fatal error occurred, no output PDF file produced!

In my unstable NixOS system configuration I have:

  environment.systemPackages = with pkgs; [
    ( texlive.combine {
        inherit (texlive) scheme-full ;
    } )
    # other packages
  ];

It works now.
