Hi Chad!

How did you proceed in getting the software installed?

If I am not wrong, the current version in the official Ubuntu repositories 
should (still) be 6.4.2-2build1 -- this is what you should normally see in 
Ubuntu's Software Center.

If you see 6.4.3 and version 7 as well, does this mean that you added the some 
Ubuntu-GIS repository?

Following links are recommended:
* <https://wiki.ubuntu.com/UbuntuGIS>
* <https://launchpad.net/~ubuntugis/+archive/ppa/>

O-kay.

Confused... :-/

Try this from the scratch (if you want):

1. remove any installed grass package, e.g. by executing in a terminal

sudo dpkg -r grass

OR, simply search & remove it within from the Software Center!


2. Add the "ubuntugis-testing" repository available in Launchpad:
<https://launchpad.net/~ubuntugis/+archive/ubuntugis-testing>.  The easiest 
way is to launch a Terminal, and execute the following:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-testing && sudo apt-get update


3. Install grass7 from either the Terminal by instructing;

sudo apt-get install grass70

OR via the Software Center (it should appear!)


4. Launch grass70 via the terminal OR via Ubuntu's menu (should be also easy 
to trace once installed!)

Gd Luck, Nikos
