[These settings are handled by apt]

If you are using sudo to run apt-get then the problem is that
sudo only passed http_proxy, and not no_proxy.  This was
considered a security issue and sudo has since been changed to
not pass any proxy settings. See #432631 for details.

You should instead make your proxy settings in /etc/apt/apt.conf

When not using sudo and testing with 0.8.10.3 both of these variables
are respected.

Please use "http_proxy" which is more commonly supported, rather than
"HTTP_PROXY".

  Aptitude seems to ignore environment variable $no_proxy

Status in “aptitude” package in Ubuntu:
  Invalid

Bug description:
  Aptitude uses the environment variables $http_proxy and $ftp_proxy for its proxy configuration, but seems to ignore the variable $no_proxy.
  This is a problem if the package server is inside the local network.

  Symptom is apt is hanging with output
  > 0% [Waiting for headers]
  when trying to update package information via
  > sudo apt-get update

  if I empty $http_proxy package update is working without any problem.
