How do I update LibreOffice to next point release in 14.04?

To get the latest version of LibreOffice (the one not directly located in the Ubuntu Repositories) add the libre ofice PPA.

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt-get update
sudo apt-get dist-upgrade

This should upgrade you to the latest version of Libre Office available. Do note that the 4.3 package is not YET added to the PPA.

The PPA mentioned by jbuch14 is bleeding edge and not for you if you just want the 4.3 LibreOffice release.

For that, use

sudo add-apt-repository ppa:libreoffice/libreoffice-4-3
sudo apt-get update
sudo apt-get dist-upgrade

This leaves you stuck on 4.3 until you decide to switch in a new repo and repeat this process but it will ensure you get all the release quality 4.3 updates without risking loading in libreoffice alpha or beta code.

See this page for what the latest ppa is.

The preferred way is to use the PPA, as answered by Jbuch14 above. The 4.3 packages aren't there yet, but should be in short order. The maintainer will have probably fixed packaging errors, (if any) and worked out the dependencies, but...

If you can't wait, and feel brave and adventurous, remove the 4.2 version, get the debs from http://www.libreoffice.org/download/libreoffice-fresh/, and install them "directly".

Here is an example of how it's done:

• removing - sudo apt-get purge libreoffice*

• downloading - LibreOffice_4.3.0_Linux_x86_deb.tar.gz

• right-click, select Extract here to extract

• installing - cd LibreOffice_4.3.0_Linux_x86_deb/DEBS; sudo dpkg -i *.deb
