I keep this bookmarked:

So, for this new 6.5 version (modified):

Now go to Sun's website and download

Then run the following commands from the terminal:

First install the required packages:
sudo apt-get install fakeroot java-package java-common
Create the Deb file for the install:
fakeroot make-jpkg jre-6u5-linux-i586.bin
Install The deb file
sudo dpkg -i sun-j2re1.6_1.6.0+update5_i386.deb
Now make Sun's java the default by running this command and selecting  it.
sudo update-alternatives --config java

$ sudo update-alternatives --config java

There are 4 alternatives which provide `java'.

  Selection    Alternative
*         1    /usr/lib/jvm/java-6-sun/jre/bin/java
          2    /usr/bin/gij-4.2
          3    /usr/bin/gij-4.1
 +        4    /usr/lib/j2re1.6-sun/bin/java <== this is the new one

Press enter to keep the default[*], or type selection number: 4
Using `/usr/lib/j2re1.6-sun/bin/java' to provide `java'.
$ java -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)

Close your browser & restart, then test again at

And it should detect 1.6.0_5:

Verified Java Version


You have the recommended Java installed (Version 6 Update 5).
