When trying to compile a LaTeX document in Ubuntu 10.04 with xelatex I get the following error message:

This is XeTeX, Version 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian)

What is wrong?

Note: I just had this problem and thought I'd post it here. – Caramdir Jul 30 '10 at 15:07
Thanks for asking and answering the question; I'm sure it will be useful to others (esp. those who arrive through Google). – ShreevatsaR Jul 30 '10 at 15:18

This is a bug in Ubuntu 10.04's textlive-xetex package: It does not depend on the lmodern package (see the Lauchpad bug report). To fix the problem just install the lmodern package, e.g. via

sudo apt-get install lmodern

(This also effects Debian Lenny: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=576599)

Moreover, I'd recommend to skip the Ubuntu packages install TeX Live directly from tug.org/texlive. – Caramdir Apr 20 '11 at 20:04
.... and this still isn't fixed (Ubuntu Server 14.04). Thanks! – Camil Staps Oct 20 '15 at 21:48
This solution works... thank you. – demented hedgehog Feb 13 at 21:53

I have installed TeXLive2010 on Ubuntu 10.04 using the ISO image file, I have no error and all things working properly. It seems that, the error is for your TeXLive installation! Try the ISO image.
