I’m looking to have Sun Java 6 Update 16 but when I install I get Sun Java 6 Update 15 not update 16
System Ubuntu Karmic 64bit
your installation says it’s update 16 not 15 any idea why???
Setting up sun-java6-bin (6-16-0ubuntu1.9.04) …
Setting up sun-java6-jre (6-16-0ubuntu1.9.04) …
Setting up sun-java6-jdk (6-16-0ubuntu1.9.04) …
I clicked on the license term screen. But it just won’t go away.
Never get to see that screen. I also pressed “Enter” key. Doesn’t work either.
Why?
I use Ubuntu 9.04.
@Anthony If you hadn’t figured it out, I had to press the Tab key to get focus on the field. Just Tab until is highlighted in red.
@Bill Guinan THE bloody TAB key – you saved my afternoon. Thanks.
thank you.
i’m always learning and this helped clear things up a lot.
i fallowed u r steps but getting this error

You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
sun-java6-jdk: Depends: sun-java6-bin (= 6-16-0ubuntu1.9.04) but it is not going to be installed
sun-java6-jre: Depends: sun-java6-bin (= 6-16-0ubuntu1.9.04) but it is not going to be installed or
ia32-sun-java6-bin (= 6-16-0ubuntu1.9.04) but it is not installable
Recommends: gsfonts-x11 but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).

Thanx for dis article.
It is really helpful.
when i try to install java :
root@naba-laptop:~# sudo apt-get install sun-java6-jdk
E: dpkg was interrupted, you must manually run ‘sudo dpkg –configure -a’ to correct the problem.
Thank you Bill for saving me from a lot of frustration. I think I tried just about every key-combo, but I never thought about pressing TAB.
Thanks !!!!! silly TAB !
Can you refer where i can updated deb package for Oracle JDK?
@Bill Guinan Thanks for the TAB key. I’m new to Ubuntu and have been struggling for 15 minutes, until I finally found this post!
Ahhhhhhh, the TAB key!!!! Thanks!
If you just installed Ubuntu Natty i386, try apt-get update first, before user apt-cache search ^sun-jdk, and everything will just be fine =)

Hi sir,
Gud afrn…
I installed Ubuntu10.4 server in my system.while installing java,i got this error message.Error is : package sun-java6-jdk has no installation candidate.
Can you tell me,how to solve and how will i install java into VMware???
reply me..
@sai: If ‘passwd’ prompts for existing password, then the root password might have already set. If you want to reset your root password, execute the below command and enter your currently logged-in password:
sudo -s
You would have switched to root, now reset the root password by ‘passwd’
—
@sai: All the installation and configuration should be done with root privileges. Switch to root executing the below command:
su – root
and enter the root password
If your machine is new, you might now have root password set. Set the root password by executing the below command:
passwd

Probably ‘sun-java6-jdk’ is upto the version karmic(9.10). It’s now ‘openjdk’ from 10.04 onwards. You might need the below command:
apt-get install openjdk-6-jdk openjdk-6-jre
Of-course sun-java6 can also be installed making some change sources.list.
@Anonymous: You could find under /usr/lib/jvm/
Thank you so much for the screen shots. It greatly assisted me while walking a computer-phobia through the process over the phone. I cannot thank you enough.
