A quick tip for Debian users who want to install and stay up to date with the latest Oracle Java 7 (JDK7): the WebUpd8 Java 7 PPA works on Debian too since the package is just an installer and all you have to do is manually add the PPA repository to the Software Sources.
As a reminder, the Oracle Java 7 PPA repository does not host any Java files but only an installer that automatically downloads and installs Oracle Java 7, like the flashplugin-installer package for instance.
To add the WebUpd8 Oracle Java PPA repository to the Software Sources in Debian (tested on Debian Squeeze, but it should work with any Debian version), use the following commands:
Code
su -
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886
apt-get update
apt-get install oracle-java7-installer
exit
