How to install LibreOffice 3.5.1 in ubuntu using PPA
What is new in LibreOffice 3.5.1
This is the second release from the 3.5 branch of LibreOffice.
It contains many exciting new features, and is the recommended version for private users.
The following notes apply:
This release is bit-for-bit identical to the 3.5.1 Release Candidate 2, so you don't need to download or reinstall if you have that version already.
The distribution for Windows is an international build, so you can choose the user interface language that you prefer. Help content is available via an online service, or alternatively as a separate install.
For Windows users that have LibreOffice prior to version 3.4.5 installed, either uninstall that beforehand, or upgrade to 3.4.5. Otherwise, the upgrade to 3.5.1 may fail.
For Windows users that have OpenOffice.org installed, we advise uninstalling that beforehand, because it registers the same file type associations.
If you run Windows 2000, you may require this update before being able to install LibreOffice.
If you run Linux, the GCJ Java variant has known issues with LibreOffice, we advise to e.g. use OpenJDK instead.
LibreOffice contains all the security fixes from OpenOffice.org in 3.3.0, and perhaps more as a side-effect of the code clean-ups.
Microsoft Office 2010 will complain that ODF 1.2 and extended documents written by LibreOffice 3.5 are invalid (but opens them still). This is a shortcoming in MSO2010 only supporting ODF 1.1.
Install LibreOffice 3.5.1 in ubuntu
Open the terminal and run the following commands
sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get upgrade
This crashed multiple times when I installed it with Ubuntu 11.14. The version included in 11.04 is rock stable.
Hopefully, 3.5 will be stable when Ubuntu 12.04 is relased.
