problems installing JRE and Eclipse

[ub1922]

I just installed UBUNTU 11.10 on my laptop.
Have connection to the Internet.

I am trying to install Java and Eclipse.
There are few problem I have encountered.

1. Eclipse does not find Java

2. While trying to install Java JRE the sudo apt-get update - could not connect to any of the servers.
More when I tried to Find best server, it gave me a message, no Internet connection. I have no problem finding packages in Mozilla. Am I missing some settings for Software Center or what?

3. I downloaded jre1.6.0_29, unpacked and now I have a folder with some files in it. How to I know that this Java JRE is installed?

Thank you for your help.

Where did you download the jre from?

Have you tried installing the openjdk from the Ubuntu Software Center?

[ub1922]

ubuntu software center cannot download anything

it gets stuck during download

[thatguruguy]

Well, that seems like the first problem to solve.

Open a terminal and type:

software-center

Let's see if we can get that problem solved.

as you said I tried openjdk again.

in the progress tab I can see

Updating Cache 
Downloaded 0 B of 14 B

it could stay like this forever

So far, so good.

Actually, close the software center, and type the following into a terminal:

sudo apt-get update

It will prompt you for your password. Post the terminal output here.

Also, please wrap the output in code tags.

I tried this as well

sometimes it gives me this
sometimes it gives me Err Unable to ....

you must close the software centre before running apt-get
