I'm trying to get a minimal LaTeX working inside a Docker container to support some documentation generation. Currently this is what I have going:

RUN wget -qO- "https://github.com/yihui/tinytex/raw/master/tools/install-unx.sh" | sh
ENV PATH "$PATH:/root/.TinyTeX/bin/x86_64-linux"
RUN tlmgr install standalone preview ucs was newtx fontaxes xcolor dvisvgm psnfss symbol

Whenever I try to compile a document, I get the error message:

Font TS1/ntxtlf/m/n/12=ts1-qtmr at 12.0pt not loadable: Metric (TFM) file not found

Here's one example document. This is generated by a tool (m.css), which is why it's using way more packages than it needs to. Modifying the docker environment is easy, but modifying the actual document is very difficult.

\documentclass[12pt,preview]{standalone}

\usepackage[utf8x]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{gensymb}
\usepackage{newtxtext}
\usepackage{xcolor}
\usepackage{array,graphicx}
\usepackage{booktabs}
\usepackage{pifont}

\begin{document}
\begin{preview}
$O(2^{N})$
\end{preview}
\end{document}

Note that my end goal here is to get the smallest Docker image that works to compile documents similar to that. Yes, I can apt-get install texlive-full and everything will work, but I'd rather figure out the minimal set of fonts and packages needed.

More generally, is there a way to go from that error message to the name of the package I need and/or the fonts that are missing? TS1/ntxtlf/m/n/12=ts1-qtmr isn't very googleable.

TeX can not find ts1-qtmr.tfm

If you issue the command 

tlmgr info ts1-qtmr.tfm

then amongst other things it reports

Packages containing files matching `ts1-qtmr.tfm':
tex-gyre:
        texmf-dist/fonts/tfm/public/tex-gyre/ts1-qtmr.tfm

so 

  tlmgr install tex-gyre

would move things along.

  • Thanks! So basically take the last part of the message (12=ts1-qtmr), cut off the font size, add .tfm, then search that with tlmgr info? Is that a good general way to find the fonts? – Robert Fraser Mar 7 '19 at 19:52
  • @RobertFraser it's a good way to find anything tex related, if you had \usepackage{wibble} and tex said it couldn't find wibble.sty then tlmgr info wibble.sty would reveal what texlive package contains that latex package. – David Carlisle Mar 7 '19 at 20:55
  • you don't need to add .tfm specifically, to see related entries including the target you could tlmgr info ts1-qtmr and also get the adjoining info for when you specify italics e.g. both texmf-dist/fonts/tfm/public/tex-gyre/ts1-qtmri.tfm and non italic forms are in tex-gyre beware do not shorten to ts1 there are hundreds for example try tlmgr info ts1-qtm – user170109 Mar 7 '19 at 22:30
