Assuming now that you have /etc/apt/soures.list edited accordingly, I
suspect there is no need for a proxy of any sort. Of course I could be
wrong if however you are behind some sort of corporate proxy-device
(squid or something else).

If the above is true and you are part of an IT team, one might think
that the IT powers that be would have setup some sort of allowance for
IT based devices to bypass corporate proxies.

If this is true - seek the help from an IT person to gather the proper
information etc.

Hi Chris,
Thank you for your reply.
Since in my place using ISA server to connect to outside world and
ISA server require windows authentication that we need to supply
Windows Domain username and password.

I use opera for browsing in my windows and when it prompt for user name
simply I enter

where MYOFFICE is my windows domain
and then on the password I type my password.

If I remove http_proxy from bash.bashrc I still can't connect to outside 

I have installed my ubuntu server (for learning purpose) under vmware.
Then I use NAT to connect to other computer.
I can ping to my proxy server and get reply.
Therefore I believe nothing wrong with the NAT.
IMHO the problem is on windows authentication when connect to the internet.
