apt-get update no go

[agila]

I am new here and what I am trying to do is installing BT4 pre-final into my 8GB USB Thumbdrive by following the instructions at infosecramblings.com.

The problem is that I can't update my distro using apt-get update.

When I do the apt-get update from the terminal, I got this;

# apt-get update
0% [connecting to archive.offensive-security.com (94.23.3.208)]

Then after awhile, I got a lot of messages like;

W:  Failed to fetch archive.... Unable to connect to archive.offensive-security.com http:

I am behind a proxy and although I have set the proxy from the K-Menu->Settings->Internet & Network->Proxy, I still can't get to update.

Dig to archive.offensive-security.com says Query: 1 Answer: 1

Browser also don't work unless I set the proxy manually in the Preference->Advance->Network.

Any help is very much appreciated.

TIA

apt-get doesn't know that you have setup a proxy.. Even though you setup proxy on the GUI side, apt-get wasn't made aware.

Here's one example: Configure apt-get to use a proxy (Ubuntu) « Technoblog.org
