The latest installation instructions for LibreOffice
Hello Linux Geeksters. As you may know, LibreOffice is an open-source popular Office Suite application, running on Linux, Windows and Mac OS X. The latest version available is LibreOffice 4.2.0 RC1, which has been released a while ago, bringing some DOCX/RTF import fixes, image transformation in SVG Import support, the SpinButton has been removed, etc. For more information, see the changelog.
In this article I will show you how to install LibreOffice 2.0 RC1 on Fedora, CentOS, OpenSUSE, Mageia and OpenMandriva.
Because it is not available via any repository, we have to download the libreoffice archive, extract it and install the rpm packages inside. Follow the instructions for your system’s architecture exactly, in order to get a successful installation.
