JRE/JDK installation onto a PowerPC form of Ubuntu.
 

Hello everyone, I am new to Linux and decided that I would make myself somewhat known here. The problem I am having is with a curb swiped Power Mac G4 from 2004 (I believe) that had been upgraded from OS9 to OSX. Prior to my heavy tinkering it did have OS9 on a 40gig HDD and OSX on the bigger 160gig HDD, I had managed to figure out how to delete and format the 40gig (with the help of a good friend who knew about Macs) and put a PowerPC friendly form of Ubuntu (10.04 Lucid Lynx) onto the 40gig. Being a Windows user since 3.1 was in use, I don't know much of Linux at all but am very lucky to even get this far.

To the point: I am trying to get a private Minecraft server going on this old machine and am in need of help to install Java on here to do so properly. Anyone know enough about this to help? I have been looking at how to do this properly for the past 5 or so hours, and finally gave up to post this thread.

Hi,

Welcome here, and thanks for keeping at least one PC out of the "Grand Landfill".

Okay, on to Java.

What you need are the Java packages from either Sun or your Repo.
The Repo, that's easy, follow the path of your distro.
The Sun packages need to be downloaded.

Next, follow these steps:

- open a console
- become Root (issue the "su -" command and supply the root password)
- locate the downloaded file, tip go to "/home/[user]/Downloads" - that'"s a possibly safe bet
- issue the following command :

an example

- copy the file

go to that folder

start the file up to install

and the JRE is installed.

To invoke...that depends...but you should be able to run Java stuff from then on...

as a humble example...

I'll keep this thread on the scope, dont worry!

Luck

*facepalms* Ok I am unable to modify the root password now even if I give the command to do so. Otherwise it will not allow me to access the root.

No problem...it's just an "astuce" as said in french... :D

Can you open a console? If so enter "su -" the hyphen is part of the entry...
Can you type the password? There is no feedback, as you're possibly aware...
Upon success, the prompt should be different.

I'll follow up...this is my "primary thread" today...

This is what I'm getting everytime I attempt to put a password in.

Hmm, okay...
You're using Ubuntu, lemme think...
Passwords (as everything in Linux) are CaseSensisive...maybe that's worth a shot? Have you ever done this (logging into a console) before?

Let's see...

You can still get an Ubuntu package ..

Or do this with the java, you downloaded : sudo ./jre-6u26-linux-i586.bin
JDK : sudo ./jdk-6u26-linux-i586.bin

I've used "sudo" before but I've never used "su -" before. Is the console same as terminal, because I've been using the terminal. Perhaps it could be the problem all its own.

edit: By the way this is the desktop version of ubuntu.

A console or terminal, both are valid names, point is that you get to see a text-only screen where you can type stuff...but, you've used sudo before, so, let's take that path...

and, to quote knudfl

is the way to do this, to be executed in the /opt folder (top level), just to keep your system "clean"

Edit
I dont have sudo on my system, I'm the only one using it and (old skool as I am ;) ) I'm more comfortable with su- ...

Story of what has been happening.

edit: Is there anyway to do this through the GUI?

I found a JDK file in the software center. Hopefully it works properly, I just need to upgrade it.

Of course there is...you're using Ubuntu, so the Softare Center should do the whole thing...of course, Sun's JRE/JDK are not in there...

And...

You're right on the mark, it seems...

Edit : I use Arch Linux, we do not have a GUI to maniplate software, everything gets done in the console...hence my "leaning towards" the console...

It will be available in Synaptic and 'Software Center' when ppa is added.

I know the feeling, I personally feel that where ever Mac is involved something isn't going to go my way.

Dont let it get you down...and, by the way:

...is NOT the Mac of 2011 of course, and Mac is HARD and SOFT in a bundle....

Personally, I feel more at ease in a console. But, that's grown over time...
