Title:
  gnome-network-properties does not set apt proxy correctly

Status in “gnome-control-center” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gnome-control-center

  Ubuntu version:
  Ubuntu 10.04.1 LTS  and
  Ubuntu maverick (development branch)

  Package version:
  Lucid: 1:2.30.1-0ubuntu1
  Maverick: 1:2.31.91-0ubuntu1

  How to replicate:
  Go to System -> Preferences -> Network Proxy (or gnome-network-properties)
  Manual, Use same for all protocols, proxy.sun.ac.za port 3128
  Ignored hosts: *.sun.ac.za and 146.232.0.0/16
  Apply Sytem-wide
  Restart computer

  Part 1:
  run: sudo aptitude update
  w/h: apt tries to use the proxy to connect to the ubuntu repository at ftp://ftp.sun.ac.za/
  w/s/h: apt should obey the ignored hosts and connect directly to this server
  workaround: comment out "Acquire::ftp::proxy "ftp://proxy.sun.ac.za:3128";"; in /etc/apt/apt.conf. Then apt connects directly to ALL ftp servers.

  Part 2: (after workaround has been applied)
  sudo aptitude install flashplugin-installer
  w/h: apt calls wget, which on its turn tries to download the flashplugin from http://archive.canonical.com directly, without using the proxy server.
  w/s/h: wget, which is called by apt, should obey the proxy rules set "system-wide" in gnome-network-properties.
  workaround: running a transparent proxy on another computer through which the traffic is routed. Or "sudo killall wget" a lot of times and let the install fail.
  The same happens when installing ttf-mscorefonts-installer, which is also called by wine and ubuntu-restricted-extras.

  This bug is present since 10.04 and affects all users on networks
  behind proxy servers. This includes university networks.

  Bug also affects:
  aptitude
  apt-get
  software-center
  wget

  This bug can be classified as a security vulnerability as access to
  update-repositories might be blocked (part 1).
