# could scrarctl be causing the error message ! LaTeX Error: File ucs.sty' not found.

I am working in Ubuntu 10.10 using Gnome. I wrote this:

\documentclass{scrartcl}
\usepackage[mathletters]{ucs}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage[usenames]{color}
\usepackage{hyperref}
\usepackage{wasysym}
\usepackage{graphicx}
\usepackage[normalem]{ulem}

\title{Papa Johns Cheese}
\date{Saturday 25 December 2010}
\author{}

\begin{document}

\maketitle
---message---

\end{document}


I get the above error message in the log file

! LaTeX Error: File ucs.sty' not found


Now I have not used LaTeX since 1993, so I went to a beginners tutorial and wrote the hello script and it worked fine when I gave the command latex hello. No error. this started with \documentclass{article} So I wondered.

The document class should not change this. Did you change nothing else at all? – Joseph Wright Dec 25 '10 at 20:36

Does locate ucs.sty (on a command line) find anything? If not, you need to install the texlive-latex-extra package (eg. via Synaptic) or simply install texlive-full.

I installed texlive-latex-extra and then tried Locate ucs.sty and find -name ucs.sty. Still did not find any file. When I tried latex PapasCheese, it gave me the "File 'ucs.sty' not found" again – Hubert Dec 27 '10 at 16:31
It works now. I tried Ubuntu Software Center and searched for latex-ucs. The file given did not have ucs in it but I installed it and then I was able to compile the PapasCheese.tex file. It only gave a warning message about using something older than 2004. Thanks for the help! – Hubert Dec 27 '10 at 18:04
