Package babel error: Unknow option

Question

I just installed pdfTeX (Tex Live 2013/Debian) on by Ubuntu 13.10 laptop, but I have problems with the babel package.

My code:

\documentclass[12ptk a4paper]{article}
\usepackage[danish]{babel}


 \begin{documenet}
  This is a test.
  \end{document}

I get this error:

! Package babel Error: Unknow option 'danish'. Either you misspelled it or  the language definition file `danish.ldf` was not found.

My babel.sty file was found here /usr/share/texlive/texmf-dist/tex/generic/babel and looks like this:

In /usr/share/texlive/texmf-dist/tex/generic/babel, I have for instance the file danish.sty.

I don't understand the error when running latex.

Can anyone help or guide me in a direction?

I did follow the instructions from a similar problem, but without any luck. I tried: sudo apt-get install texlive-lang-danish and I got among other things this:

E: Package 'texlive-lang-danish' has no installation candidate

It works with a diffrent version of texlive.
