E: Invalid operation sun-java6-jdk

Answer 1

As I can see you forgot the "install" command.

sudo apt-get install <<type packages here>>

For example:

sudo apt-get install ubuntu-restricted-extras chromium-browser python

And the full code for installing GavaJava:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Answer 2

Look on this website: http://www.ubuntubuzz.com/2012/01/sun-java-6-now-can-be-installed-on.html

It will explain everything from Java being removed from the Ubuntu repository to installing it via PPA.

Install Sun Java 6 on Ubuntu via PPA Of course, this news brings some panic to many Ubuntu users, but don't worry! You can still install Sun Java 6 via PPA:

sudo apt-add-repository ppa:flexiondotorg/java
sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-plugin

The above PPA contains Sun Java 6 package for Ubuntu 10.04 Lucid Lynx to Ubuntu 12.04 Precise Pangolin!

Answer 3

You're missing the install command.

sudo apt-get install sun-java6-jdk sun-java6-jre

I don't think this is going to solve your problem of installing this package, however, as I think it has been removed from the standard repositories per license requirements. You'll have to research a third-party location or install manually.

Answer 4

i needed although the 6.9.1 Edition (for ruby support) available here and i needed therefor the older java edition. So i went to the oracle site and searched for the older version (warning you need an oracle account). Execute the downloaded *.bin file and move the files to the ubuntu jvm dir

sudo mv jdk1.6.0_32 /usr/lib/jvm/

and enable jvm

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_32/bin/javac 1
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_32/bin/java 1
sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_32/bin/javaws 1

sudo update-alternatives --config javac
sudo update-alternatives --config java
sudo update-alternatives --config javaws

now check java version ready ;) i got the infos from here
