.....

I solved like this:
sudo gedit /etc/apt/sources.list
Delete the line that it is causing the mal formed line error.
Find the lines where canonical repositories are commented with #
Uncomment lines.
Save file
Execute again
sudo apt-get update

Try again installing with
sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk
