The Drupal import_html module needs tidy and xsl. These are not installed by default on a ubuntu 6.06 server. The solution was easily found on Soledad's blog.
XSL support in php5 is deactivated by default. Go to Synaptic Package Manager and search for php5-xsl. Mark the package for installation, apply the changes and once it's finished, don't forget to restart the server!
sudo /usr/sbin/apache2 -k restart
