Word/Powerpoint equivalent

I am a new user of the raspi and want to make it a portable computer. So far, I have not been able to download and use applications from the internet. Primarily I want to be able to view/edit my word, excel and powerpoint files. Is there a built in viewer in in the raspian distro or an application I can download to accomplish these tasks? Thank you for any help you can provide.

At the Command Line

sudo apt-get install libreoffice


The main page of Libre Office: https://www.libreoffice.org

Libreoffice seems like the perfect solution but, after 3 attempts, it will not install. It gives me errors:

"The following packages have unmet dependencies:
default-jre-headless : Depends : openjdk-6-jre-headless (>= 6b23~pre8-2~)

Then it lists the applications of libreoffice and claims that "it is not going to be installed" for each one.

Is there anything else I have to install before this?

Please try

sudo apt-get update

before running

sudo apt-get install libreoffice

This will ensure the list of available programs on your raspi matches the current list on the main server.

Updated but same result.

Figured it out... Needed to expand partitions of flash card. I had been holding off for a new sd but am too impatient so expanded; and it worked!
