Yesterday I bought a new laptop and installed MikTeX. Today I tried a minimal Beamer document and it failed to run. Other, non-Beamer, TeX files work OK. Also OK are Beamer files without mathematics. What am I doing wrong?

Here is the .tex file:

\documentclass{beamer}

\begin{document}
\begin{frame}

  $\ell$     <- with only this line, no problem

   $l$       <- this line causes the whole thing to fail    

\end{frame}
\end{document}

The console output suggests that "makepk" is the culprit. Here is the start of the corresponding log file:

I'm a non-technical person so none of this makes sense to me. Is there an easy or obvious fix??

    Run updmap on a command line, or run in the miktex console (user mode) the task to recreate the font maps. Commented Mar 10, 2018 at 20:18
  • @UlrikeFischer I have no idea what that means or how it works, but it worked. Thanks!

Run updmap on a command line.

Or run in the (new) miktex console (user mode) in the tasks menu "Refresh font map files".

  • I was having the same problem and this mysterious incantation fixed it (thank goodness for stackexchange). Can anyone explain what is happening here and what updmap does to fix it?
