The recent conflict between Openoffice.org and The Libre Office community members leave users a bit confused about the future of Openoffice. With the arrival of Libre Office, we might see a more dynamic development of the much loved office suite OpenOffice in form of Libre Office. I would recommend using the test version of Libre Office to see the direction it is going in and build a community around it.
In order to install LibreOffice you have to completely uninstall OpenOffice.org first. Open Ubuntu menu –> Accessories –> Terminal and type the following:
sudo apt-get remove openoffice*.*
Then download latest tar.gz archive containing set of .deb packages of LibreOffice components:
wget http://download.documentfoundation.org/libreoffice/stable/3.3.2/deb/x86/LibO-SDK_3.3_Linux_x86_install-deb_en-US.tar.gz
When downloaded unpack archive contents using command:
tar -zxvf LibO-SDK_3.3_Linux_x86_install-deb_en-US.tar.gz
And install LibreOffice .dep packages all-at-once:
sudo dpkg -i en-US/DEBS/*.deb
if your ubuntu connected directly to the internet you can install it directly from the PPA Libreoffice, follow these steps
add PPA and install libre office to your software sources or run the command below in terminal :
sudo add-apt-repository ppa:libreoffice/ppa<br /> sudo apt-get update && sudo apt-get install libreoffice
Now to make it appear a tad nicer under your desktop environment of choice: -
Ubuntu users should run
sudo apt-get install libreoffice-gnome
congratulations libreoffice ready to use on your Ubuntu OS
Hope it helps!
