Hi

I'm aware of the existence of similar threads on this forum. But any of replies mach to my problem.

I'm using Ubuntu 10.4 and I hadn't problems with fonts till I've decided to use XeLaTeX instead of LaTeX (cf http://tex.stackexchange.com/questions/12347/typesetting-a-document-using-arabic-script/12358#12358). The problem is that I'm not able to compile any .tex document using XeLaTeX, as well as properly display XeLaTeX documentation. As I've learn thanks to mentioned thread, XeLaTeX uses the fonts availables in general in the system.

I was trying yo read fontspec documentation, but it opens in pdf with a lot of white gaps and terminal output (quite long) consist mostly of errors. This are just few lines of it:

Error: Missing language pack for 'Adobe-Japan1' mapping 
Error: Unknown font tag 'F5.1' 
Error (24124): No font in show 
Error: Unknown font tag 'F5.1'

I was trying to compile simple XeLaTeX file:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Linux Libertine O}
\begin{document}

Hello World!
\end{document}

without succes. This is terminal output of compilation:

I can't find Linux Libertine O. Searching for otf- by aptitude gives as result:

So font in question is not just uninstalled, but not available, if I'm not wrong. Does it mean that I lack some repositoires?

I was trying also to apply solution from the thread How do I reinstall default fonts?, but the result is:

maria@maria-laptop:~$ sudo apt-get install msttcorefonts
[sudo] password for maria:

maria@maria-laptop:~$ 

It seems that is not a usual problem for use of XeLaTeX; nobody in the mentioned thread suggested instalation of anything else than TeX Live.

Thanks in advance
