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'
UPDATE:
apt-cache search openoffice.org
apt-cache search openoffice.org
sudo apt-get update
then try installing adain
