Hi,

    I'd like to upgrade my distribution with apt-get and I'm having a bit of
trouble getting it to work with our network http proxy server. I've looked
through the debian-user archive and, accordingly, have tried:

http_proxy="http://[hostname]:[port number]"
export http_proxy="http://[hostname]:[port number]"

before running dselect, but I still get the error:

Err http://http.us.debian.org stable/main Packages
Could not connect to [host] (IP address)
...


The network works fine (I can ssh to the http proxy if I want). Is there 
something else I need to do first? Thanks,
