Octave won't install on Lubuntu 14.04.3 LTS

[Steven Evans]

Octave Team,
    I tried to install Octave on my Linux system, but was unsuccessful.  I'm running Lubuntu 14.04.3 LTS, and Octave can be found in the Lubuntu Software Center.  However, after trying to install, I received an error message stating that I have broken packages.
    I then tried to install Octave from the terminal by typing the following commands:

sudo apt-add-repository ppa:octave/stable
sudo apt-get update
sudo apt-get install octave
	

    After doing so, the following prints to the screen:

Reading package lists... Done
Building dependency tree      
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).


    After that I typed "sudo apt-get -f install" at the prompt.  I then receive the following:


Reading package lists... Done
Building dependency tree      
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 octave : Depends: libarpack2 (>= 2.1) but it is not going to be installed
          Depends: libcholmod2.1.2 but it is not going to be installed

          Depends: default-jre-headless but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


    I greatly appreciate your efforts to provide Octave to the world.  I'm sending this message because I am very interested in using Octave, and during installation, I was instructed to contact the Octave Team if installation ran into any problems.
    Please let me know what I need to do in order to install Octave on Lubuntu, and I want to thank you, once again, for developing Octave.

Sincerely,

Steven Evans
