I have texlive installed (via the repositories) on ubuntu 13.10. The version number it lists is 2013.20130722, so I figure this is texlive 2013?
I have a Biolinum font file with path /usr/share/fonts/opentype/linux-libertine/LinBiolinum_R.otf.
Trying to load
\usepackage[T1]{fontenc}
\usepackage{libertine}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[greek=n,biolinum]{libgreek}
\usepackage{mathastext}
everything is typeset as expected, except that all Greek letters are replaced with a space.
Is this a problem with my texlive installation, with the font file, the libgreek package or something else?
Edit. The code is
\documentclass[12pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage{libertine}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[greek=n,biolinum]{libgreek}
\usepackage{mathastext}
\begin{document}
$\Gamma$
\end{document}
and libertine-legacy is installed (correctly, I hope).
\maketitle
, and the title uses no Greek letters. In any case, I followed the installation instructions (see comment on the answer below). What more need I do to install the package correctly?
