I need help installing some 3rd party programs

[5150Jim]

As you can probably tell, I'm new to Linux. I love it but I'm really confused about installing 3rd party programs. I have been around PCs since DOS 1.0. I had Vic 20s & C-64s before that.
Okay, sorry I digress. I hate WIN 8 but WIN 7 was okay & I have dual boot on this laptop but now WIN 7 is having problems but that's another topic. We have 4 laptops & I have Linux Lite on 3. But I'm not grasping how to get something as easy as iTunes on the laptop to work. Also last night I tried to install Java but not even sure where to go to & enable it.
I did use forum & this info:

Hello!

Yes, the procedure listed in the manual was the one I followed. That procedure didn't work, so I did what I do WHENEVER *ANYTHING* stumps me: I started Googling. I found THIS URL:

http://forum.pcmech.com/showthread.php?t=231503

The procedure spelled out at that URL did the trick. Oracle's Java check (JRE 7 Update 51, the latest one) now passes...

But when it said to
Create a symbolic link to the libnpjp2.so file in the browser plugins directory
Go to the plugins sub-directory under the Firefox installation directory
cd <Firefox installation directory>/plugins
Create plugins directory if it does not exist.
Create the symbolic link
ln -s <Java installation directory>/lib/i386/libnpjp2.so

I was lost.
So I guess what I need is a little more hand holding as I go through the installations.
I still can't print from my laptop but that's for another day also.
So I have downloaded both iTunes & Java but can use either.
Can someone tell, is there an easy fix.
TNX, Jim

ITunes and Linux don't work very well together.  I have read where some folks get it to run under WINE but I had zero luck.  Linux has decent music managers; however, if you're trying to manage Apple hardware (iPhones, iPods, etc.) you're facing a challenge.  I keep Win 7 running for this exact reason.  Why do you require Java? 

Here's a synopsis I found on Google:

To 5150Jim,

You're off to a bumpy start.  Let's try to smooth that out.

1) You can install the Java web applet via Lite Software Menu->System->Lite Software.

2) When in Lite Software, also consider installing Clementine (Music Player) and gtkpod (iDevices Manager) instead of iTunes.

3) What is the make and model of your printer?  Is your laptop the only computer that you cannot print with?  How did you try to connect to the printer?  Wirelessly, via a network connection, via a USB cable?

Read 'Status of Supported Hardware' - http://www.gtkpod.org/wiki/Home here first before proceeding to see if your device is supported in gtkpod.

I had a web training to do last night (Cisco WeEx Meeting) for a company that I work for part time & I clicked the link they email me & it said:
Java Not Enabled

This WebEx recording cannot be played because Java is not enabled in your Web browser or you don't have JVM installed.
- To enable Java: refer to your browser's online Help
- To install JVM: access <www.sun.com> to download

Okay, still not very smooth. So I'm doing one thing at a time & tried Java by Menu->System->Lite Software
and got an error.

Updating sources has failed.

Refer to /var/log/lite-software.log

for more information.

Try this.  Open up a terminal (Menu->Accessories->Terminal).  Copy and paste in the following two lines, one at a time.

Code:

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

Then try opening Lite Software again.

I'm not going to worry about my daughter's ipod right now because it says on the gtkpod site.

iOS devices up to and including iOS4
    CANNOT be written to unless a binary-only blob is used

As for my printer:
Canon MG5422
I have 1 of the 4 laptop that prints. That would be the WIN 8 & it's wireless. I even tried to install the drivers with the USB cable on the others but none will print with the cable or wireless.

I have even tried to install it on this laptop I'm typing on by going through the terminal to no avail.
OH wait... It does print under the WIN 7 partition, or at least it did. Because I can get anything to work in WIN 7 right now.

I was pleased a couple of weeks ago when my HP printer was immediately picked up by LL and was ready for use. Then this morning it suddenly wouldn't print. I found I had to go into Printers and Enable it, for some reason. Not sure why that happened, but I'm just mentioning the possibility.
