Which Java do you want? I downloaded mine from java.sun.com, but others are available.

[infla]

oh? I don't know :P

just a normal java version i guess :P

[infla]

well, i've downloaded something there, but how can i install it?

[infla]

oh, wait, I think that I got it.

you can just install this:

sudo atp-get install ubuntu-restricted-extras

it installs java, flash, media codecs and fonts.

Well, it depends on what you want, but personally I like the Sun java package:

If you want the Java Runtime Envirnoment:



$sudo aptitude install sun-java6-jre


If you need the Development Kit:



$sudo aptitude install sun-java6-jdk


If you want the plugin for your browser:


$sudo aptitude install sun-java6-plugin


I hope this is useful for you.

San_SS,


i can't do that, because:
/var/lib/dpkg/lock

that is locked (i'm not permitted to do that)

so I think that i have to unlock it with chmod? but what was the code for that?

Are you already installing something? Is synaptic running? If not, just reboot, and it should be solved.

okay, i'll try

[infla]

no, i still can't.


E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

[infla]

anyone?

[Soul-Sing]

anyone?

if all other -apt/software manager/synaptic etc is closed


sudo rm /var/cache/apt/archives/lock

sudo apt-get update

Did you sign the license that comes with sun java? If not sometimes linux comes with this errors....

Check System, Administration, Software Sources, and make sure you have the multiverse repository enabled.

The version of Java you can install from the repos is dated.

You may want to either install OpenJDK or follow the instructions here:
