Installing Java on Ubuntu Edgy Eft 6.10

You need to ensure that apt-get is pointed at the right place. In /etc/apt/sources.list add in the following:

deb http://us.archive.ubuntu.com/ubuntu dapper main restricted
deb http://us.archive.ubuntu.com/ubuntu dapper universe multiverse

After this have apt updates its repository:

sudo apt-get update

And finally, just tell it to install Java 1.5:

sudo apt-get install sun-java5-jdk

You can check Java is installed correctly by typing:

java -version
