Anyone who has used Ubuntu has used LibreOffice, even if just trying it out. LibreOffice is based off of OpenOffice and it works better in some senses. LibreOffice 3 is the default version, even though LibreOffice 4 is officially tested and has an official PPA.
Personally, I prefer LibreOffice 4 over 3 and I wanted to upgrade. I found out how to do this, but it took a little searching and fixing. I have compiled a complete way to upgrade LibreOffice, and hopefully it makes your process easier than mine was.
First off start up terminal. This shouldn’t be too hard, if you can’t find a link to it (should be at least one) just push
Ctrl+Alt+T and terminal should open up quite quickly. If it doesn’t, you have a real problem and should look around for an answer.
Once terminal is open, enter this command:
sudo add-apt-repository ppa:libreoffice/libreoffice-4-0.
After you enter your password it will display some info about the PPA and ask for confirmation. Just hit enter and it will add the PPA and an Ubuntu keyring.
Once the PPA has been added, enter this command:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade.
This will check for updates and upgraded versions of programs already installed. The dist-upgrade part will upgrade LibreOffice from version 3.x to version 4!
The upgrade will be downloaded and installed, but be sure not to interrupt it, as this could cause unwanted problems. Once this process completes, you can use LibreOffice 4!
LibreOffice 4 is chock-full of new features, most notably, extended support for Office formats.
You can access the main page at libreoffice.org. The page has some info on the new version here and includes info on the new features.
Foremost in the new features is the ability to read/write Publisher and Visio files through LibreOffice Draw. While it doesn’t work quite as well as Publisher for editing .pub files, it works great for what it’s meant for. I haven’t tested out the Visio support, but I’m sure it works great.
Another very cool feature is the fact that LibreOffice supports Firefox Personas! This means you give LibreOffice the exact look you like. If you like LibreOffice, I suggest you upgrade.
