Unable to run Blender on Ubuntu In pretty new to blender, and I installed the latest Ubuntu image on a machine to test it out. When I try to launch it from the console, I get the following error:

It's not clear from your question whether you installed Blender via the command line or by downloading the package. 

I'm guessing you installed via the command line as you are encountering dependency issues. 

Try downloading the latest release from blender.org, then just double click the executable icon 'blender' in the 'blender-2.7*' folder, or navigate to that directory and from the command line run: ./blender

To reiterate the comment above, you shouldn't be running this as root.
