Font Issues

[Xaldew]

Given the following beamer:

\documentclass[aspectratio=1610]{beamer}
\usepackage{fontspec}
\usepackage{iftex}
\usepackage{xcolor}
\usepackage{caption}
\usepackage{amsmath}

\ifLuaTeX\else
  \usepackage[utf8]{inputenc}
  \usepackage[T1]{fontenc}
\fi

%%%%%%%

\hypersetup{colorlinks,linkcolor=,urlcolor=lundbronze}

\title[]{\huge{}Test Beamer}
\author[]{John Doe}

\begin{document}

\begin{frame}[plain]
  \titlepage%
\end{frame}

\begin{frame}[fragile]{Test}
  $rank_{1}(B, n) = I + II + III$
\end{frame}

\end{document}

Note in particular that we have selected to use the lu fonts, AGaramond and FrutigerLTD. Even when these fonts are installed however, the above beamer will fail to compile with the error messages:

XeLaTeX:

The only way I have found to 'fix' this issue is to use this tool https://tug.org/fonts/getnonfreefonts/ to install the garamond and garamondx font specification. Thus, this should probably be documented in the README if it is desired to use these fonts.

Sounds like a good idea! PR is welcome indeed on the README.
