Java Runtime Environment botched installation

I used instructions from the following tutorial in order to install JRE:

http://ubuntu-tutorials.com/2006/11/20/how-to-install-java-runtime-environment-jre-with-firefox-plugin-ubuntu-6061-610/

Using apt-get, I downloaded and partially installed the packages, then, when I came to the Sun licence agreement that opened up in the console, I scrolled down to the bottom of the message and could find no way to agree to the terms of the installation, as clicking on the "Ok" text did nothing, nor did hitting the space or enter keys. So I closed the console, which left me with a broken Java package.

One partial solution would be to add the message "hit the Tab key to agree to these terms" or some such at the bottom of the installation screen in the Linux console.
