The question very simple and short. I am following this article to install OpenOffice headless:
sudo apt-get install openoffice.org-headless openoffice.org-writer openoffice.org-draw
And I get the following error :
Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package openoffice.org-headless E: Couldn't find any package by regex 'openoffice.org-headless'
apt-cache search openoffice.org
