Title:
  debian-installer preseed "d-i mirror/http/proxy" sets env http_proxy

Status in debian-installer package in Ubuntu:
  Triaged
Status in debian-installer package in Debian:
  New

Bug description:
  Binary package hint: debian-installer

  Description:	Ubuntu lucid (development branch)
  Release:	10.04

  In my preseed file I set "d-i mirror/http/proxy string http://apt-
  cacher:3142/", this is an apt-cacher-ng proxy. This works correctly
  for installing the system.

  I expect "d-i mirror/http/proxy" to only apply to the debian installer
  http proxy (apt proxy), and all other http applications, e.g., wget,
  curl, lynx to not use that setting.

  Instead when I run applications from the Kickstart %post section, all
  HTTP connections are proxied; curl, wget, lynx, hg (mercurial),
  everything. Once the system installs and reboots all is good, the only
  remanence of the mirror/http/proxy setting is in /etc/apt/apt.conf,
  which is fine (though I think that should be configurable too).
  mirror/http/proxy is setting the environment variable http_proxy.

  Repo:
  Set "d-i mirror/http/proxy string http://apt-cacher:3142/" in a preseed (use your local mirror).

  Use a Kickstart post section like this:
  %post --interpreter=/bin/bash
  exec < /dev/tty3 > /dev/ttyS0
  chvt 3
  (
  echo "## http_proxy = $http_proxy"
  echo "## lynx dump head"
  lynx -dump -head http://example.com
  echo "## wget"
  wget -O /root/test http://example.com
  ) 2>&1 | /usr/bin/tee /var/log/post_install.log
  chvt 1

  After install check /var/log/post_install.log and it will look like:
  ## http_proxy = http://apt-cacher:3142/
  ## lynx dump head
  HTTP/1.1 403 Forbidden file type or location

  Server: Debian Apt-Cacher NG/0.4.6
  ## wget
  --2010-04-22 09:29:10--  http://example.com

  Proxy request sent, awaiting response... 403 Forbidden file type or location
  2010-04-22 09:29:10 ERROR 403: Forbidden file type or location.

  The workaround for me it to reset $http_proxy at the top of %post:
  export http_proxy=""
  Then all the applications that use http behave normally.

  Suggestion:
  Don't set $http_proxy with "d-i mirror/http/proxy", maybe set $apt_http_proxy if d-i needs an environment variable. For users that need a general proxy a setting like "d-i http/proxy" could be created.
