LibreOffice is the successor to OpenOffice.org Novell Edition.
The day The Document Foundation announced the fork (LibreOffice) of Oracle controlled OpenOffice most GNU/Linux distributions, including Ubuntu, announced support for it. Most major distros will use LibreOffice as the default productivity suite.
The following steps allow the addition of the ppa and the installation of LibreOffice:
Warning: This installs from a ppa and not from the official Ubuntu repository, hence there still might be problems with either the software itself, or the installation process. The installation will remove OpenOffice.
Optionally OpenOffice can be removed with the command
sudo apt-get purge “openoffice*”
on the commandline. (The installation below should remove the OpenOffice packages automatically, however, it seems more stable when the removal command above is used).
The LibreOffice ppa can be added on Ubuntu 10.10 and 10.04 with
sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
Libreoffice can then be installed with
sudo apt-get install libreoffice
Depending on the Desktop that is (Gnome or KDE), the following command is necessary:
sudo apt-get install libreoffice-kde
sudo apt-get install libreoffice-gnome
