How To Install LibreOffice 3.6.4 On My OS / Ubuntu 12.10 Using DEB Package

Step 1 : Download LibreOffice 3.6.4 :

1. Download LibreOffice 3.6.4 from the official downlad page: https://www.libreoffice.org/download/
2. Note : Please change system, version or language -> Linux (deb): x86 or x86_64

Step 2 : Unistall LibreOffice (old version)
Open a Terminal (Ctrl+Alt+T), and uninstall LibreOffice (old version), from the command line of the terminal window, enter the following command :

dnd@riyaniezt:~$ sudo apt-get purge libreoffice*
dnd@riyaniezt:~$ sudo apt-get autoremove

Step 3 : Install LibreOffice 3.6.4 (new version)

1. After downloading the installer archive file (LibO_3.6.4_Linux_x86_install-deb_en-US.tar.gz), use Nautilus to decompress it in a directory of your choice (your Desktop directory, for example).
2. After decompressing it, you will see that the contents have been unpacked into a directory called “LibO_3.6.4.3_Linux_x86_install-deb_en-US”. Open a Terminal (Ctrl+Alt+T), and change directory to that directory, enter the following command :

   dnd@riyaniezt:~$ cd /home/dnd/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/
   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US$

3. The directory contains a subdirectory called DEBS. Change directory to the DEBS directory, enter the following command :

   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US$ ls
   DEBS  readmes
   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US$ cd DEBS/
   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/DEBS$

4. To install Libre Office, enter the following command (you will be prompted to enter your root user’s password before the command will execute):

   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/DEBS$ sudo dpkg -i *.deb

5. 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:

   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/DEBS$ cd desktop-integration/
   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/DEBS/desktop-integration$

6. Now run the dpkg command again:

   dnd@riyaniezt:~/Desktop/LibO_3.6.4.3_Linux_x86_install-deb_en-US/DEBS/desktop-integration$ sudo dpkg -i *.deb

7. The installation process is now completed, and you should have icons for all the LibreOffice applications in your desktop’s Applications/Office menu.
