Answer 1

Remove folder java from /usr/bin and try again

Answer 2

if you need to install java in Ubuntu, you can try using following command and you will get oracle-java-installer in your synaptic package manager, click it and install it.

sudo add-apt-repository ppa:webupd8team/java

Else try following steps

 $ wget http://download.oracle.com/otn-pub/java/jdk/6u34-b04/jre-6u34-linux-i586.bin
 $ chmod u+x jre-6u34-linux-i586.bin
 $ ./jre-6u34-linux-i586.bin
 $ sudo mkdir -p /usr/lib/jvm
 $ sudo mv jre1.6.0_34 /usr/lib/jvm/
 $ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jre1.6.0_34/bin/java" 1
 $ sudo update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/usr/lib/jvm/jre1.6.0_34/lib/i386/libnpjp2.so" 1
 $ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jre1.6.0_34/bin/javaws" 1

Answer 3

Instead of Step 4 : 4. mkdir -p /usr/lib/jvm /usr/bin/java /usr/bin/javac /usr/bin/javaws

Just use

$mkdir -p /usr/lib/jvm

and make sure that you are moving the files to usr/lib/jvm , for that use

$mv -v jre1.6.0_34 /usr/lib/jvm/

so that you can see the details and after installation change the configuration of java and javaws by :

$update-alternatives --config java

select from the option similarly ,

$update-alternatives --config javaws

this should work if you have already another java installed

Answer 4

The issue is that you have created a folder named "java" in /usr/bin . Remove the folder from /usr/bin and run the command again.
