1) After downloading the installer archive file, use Nautilus to decompress it in a directory of your choice (your Desktop directory, for example). After decompressing it, you will see that the contents have been unpacked into a directory called LibO_3.3.0rc1_Linux_x86_install-deb_en-US. Open a Nautilus file manager window, and change directory to that directory.
2) The directory contains a subdirectory called DEBS. Change directory to the DEBS directory.
3) Right-click within the DEBS directory and choose “Open in Terminal”. A terminal window will open. From the command line of the terminal window, enter the following command (you will be prompted to enter your root user’s password before the command will execute):
sudo dpkg -i *.deb
4) The above dpkg command does the first part of the installation process. To complete the process, you also need to install the desktop integration packages. To do this, change directory to the desktop-integration directory that is within the DEBS directory, using the following command:
cd desktop-integration
Now run the dpkg command again:
sudo dpkg -i *.deb
The installation process is now completed, and you should have icons for all the LibreOffice applications in your desktop’s Applications/Office menu.
Installation of LibreOffice on Fedora, Suse, Mandriva and other Linux systems using RPM packages
The instructions here are for installing LibreOffice in US English, on a 32-bit system; there will be slight differences in some directory names if you are installing LibreOffice on a 64-bit system, but the process is basically the same and – hopefully – you will not find these instructions difficult to follow.
For instructions on how to install a language pack (after having installed the US English version of LibreOffice), please read the “Installing a Language Pack” section.
After downloading the installer archive file, use Nautilus to decompress it in a directory of your choice (your Desktop directory, for example). After decompressing it, you will see that the contents have been unpacked into a directory called LibO_3.3.0rc1_Linux_x86_install-rpm_en-US. Open a Nautilus file manager window, and change directory to that directory.
2) The directory contains a subdirectory called RPMS. Change directory to the RPMS directory.
3) Right-click within the directory and choose “Open in Terminal”. A terminal window will open. From the command line of the terminal window, enter the following command (you will be prompted to enter your root user’s password before the command will execute):
For Fedora-based systems:
su -c ‘yum install *.rpm’
For Mandriva-based systems, enter the following commands (enter your root user’s password when prompted):
su
followed by
urpmi *.rpm
For other RPM-using systems (Suse, etc.):
su rpm -Uvh *.rpm
4) The above command(s) does the first part of the installation process. To complete the process, you also need to install the desktop integration packages. To do this, change directory to the desktop-integration directory that is within the RPMS directory, by entering the following command at the command line of a terminal window:
cd desktop-integration
Now run the installation command again:
If you have a Fedora system, execute this command:
su -c ‘yum install libreoffice3.3-redhat-menus-3.3-1.noarch.rpm’
If you have a Suse system, execute this command:
su -c ‘rpm -Uvh install libreoffice3.3-suse-menus-3.3-1.noarch.rpm’
If you have a Mandriva system, execute the following command from the command line of a terminal window (enter your root user’s password when prompted):
su
Then execute this command:
urpmi libreoffice3.3-mandriva-menus-3.3-1.noarch.rpm
The installation process is now completed, and you should have icons for all the LibreOffice applications in your desktop’s Applications/Office menu.
Notes Concerning Desktop Integration for Linux Distributions Not Covered in the Above Installation Instructions
It should be easily possible to install LibreOffice on other Linux distributions not specifically covered in these installation instructions. The main aspect for which differences might be encountered is desktop integration.
The desktop-integration directory also contains a package named libreoffice3.3-freedesktop-menus-3.3-3.noarch.rpm. This is a package for all Linux distributions that support the Freedesktop.org specifications/recommendations (http://en.wikipedia.org/wiki/Freedesktop.org), and is provided for the optimal installation of other Linux distributions not covered in these instructions.
Nowadays, most Linux distribution comply with the Freedesktop.org specifications. But, at the time the package was added, many distributions did use their own methods for making their desktop environments aware of installed/removed applications, and had their own methods for registering MIME types.
The Freedesktop.org specifications/proposals standardize this to use some well-known paths and utilities to update that information.
Affected are the icon theme specification, the MIME types specification and the desktop files specification (application launcher definitions).
To install the desktop integration on such systems, use the following command (you will be prompted to enter your root user’s password beforehand):
su rpm -Uvh libreoffice3.3-freedesktop-menus-3.3-3.noarch.rpm
