LibreOffice 5.3 comes with plenty of new features. The most awaited ribbon interface which is a immensely popular in Microsoft Office is now available in the latest release.
INSTALL LIBREOFFICE 5.3 IN UBUNTU, LINUX MINT, AND ELEMENTARY OS
LibreOffice 5.3 is not yet propagated into the official repositories. Therefore apt-get command will not fetch the latest version. If you already have LibreOffice installed, you should be having version 5.1 as of today (Feb 8, 2017). You can check your LibreOffice version by opening one of the applications from the suite, then click ‘Help’ > ‘About’.
UNINSTALL OLDER VERSION OF LIBREOFFICE
STEP 1: Launch ‘Terminal’
STEP 2: Run the following command. Elementary OS users first may need to enable PPA before attempting the below command. This command will remove the LibreOffice suite from your PC.
sudo apt-get remove libreoffice-core
STEP 3: Finally, we shall clean the configuration files using purge command:
sudo apt-get remove --purge libreoffice-core
That’s it. Older version of LibreOffice is now uninstalled from your PC. You can go ahead and install LibreOffice 5.3.
INSTALL LIBREOFFICE 5.3
STEP 1: Since PPA doesn’t have the 5.3 version yet, you need to download the debian binary package (.deb) from official website.
Download LibreOffice 5.3 64-bit version
Download LibreOffice 5.3 32-bit version
STEP 2: I will assume that the downloaded file goes to ‘Downloads’ directory. Extract the contents.
STEP 3: Launch ‘Terminal’.
STEP 4: Navigate into the Downloads directory.
STEP 5: Use ls command to see the folder contents:
STEP 6: Copy the folder name which was extracted. You have to select the file name and then right-click ‘Copy’.
STEP 7: In my case, it’s a 64-bit version. So I would go into the LibreOffice_22.214.171.124_Linux_x86-64_deb directory.
STEP 8: Now go into DEBS directory where all the installation files are located.
STEP 9: Finally run the dpkg command. and you have finished installing libre Office 5.3 on your computer. Enjoy.
sudo dpkg -i *.deb
