Brand new week, brand new morning but my woes with Linux installation continues. I tried all sorts of distros but failed to get a working OS.  Finally it seemed that in my machine, Ubuntu versions 13.04 gives "buffer overrun"  problem. I tried all the variants of 13.04.



First I try to update the Lubuntu 13.04. Yeah, back to it again:

I reinstall cntlm  and try to get it working following the instructions from here:

http://zipizap.wordpress.com/tag/cntlm/

9:28 am:  Done installing cntlm.

What I am doing now is just do this to see whether apt-get works:

sudo  nano /etc/apt/apt.conf  and add the following line:

Acquire::http::Proxy  "http://rushadf:0302@127.0.0.1:3128";

 Now I put the command:
sudo apt-get update

show 0% waiting for headers and just hangs up there
Does not work. So I close the terminal and try again.

It's still not working. Now let's try this:

sudo vi /etc/bash.bashr

Add your proxy server details in the following format

export http_proxy="http://username:password@proxyhost:port/"

export ftp_proxy="http://username:password@proxyhost:port/"

It's still not working.

I close the terminal and try again to see what happens. NO! still not working!

Now I try this:

Some releases sudo is configured in such a way that all environment variables all cleared when running the command. To keep the value for your http_proxy and fix this, you need to edit /etc/sudoers, run:

visudo 

Then find a line that states:

Defaults env_reset

and add this after it: 

Defaults env_keep = "http_proxy ftp_proxy"

  Now try apt-get again. Nah still not working.
Let me have a system reboot and check. After system reboot it is working. So does it seems that it might have worked right after the first step? who knows!
