Installing Sun JDK 6 on Ubuntu 10.04

The Sun JDK can be installed on Ubuntu by adding a repository and installing with apt-get. The following works with the latest versions of both at the time of writing:

sudo add-apt-repository "deb lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk

If the command add-apt-repository is missing, install it with the following command:

sudo apt-get install python-software-properties

With the alternatives system in place, the Java executable is automatically available:

/usr/bin/java -> /etc/alternatives/java
/etc/alternatives/java -> /usr/lib/jvm/java-6-sun/jre/bin/java

Setting up JAVA_HOME can now be done by editing /etc/profile and adding to the bottom:

export JAVA_HOME=/usr/lib/jvm/java-6-sun

    Thank you very much for posting this tutorial.
    However i am having a problem with the installation. This is the error i get:
    Package sun-java6-jdk is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source
    E: Package sun-java6-jdk has no installation candidate
    Can you please help me out? Everywhere i read the same thing: Sun Java has been deprecated.No longer in use
