You should not use Oracle Java JDK (which was Sun Java JDK previously) as first choice, as after version 7 this summer, it isn’t the reference implementation any more. You should use OpenJDK instead, which is the new reference implementation.[1]

Oracle have changed the licens of Oracle Java JDK, so no one are allowed to redistribut it any more.

So, in Ubuntu/Debian you should remove the old Sun Java JDK and install the new Open JDK, which is in the repositories. [2]

apt-get –purge remove sun-java6-jre && apt-get install openjdk-7-jre

You might want to check your old software that you have runned with Sun Java so it still works[3]. If they stop working, just download and install Oracle Java JDK from them.
