title: debootstrap through authenticated proxy
body: <p>I am to install debian on my PC by 'from other linux' method and I run into problem with debootsrapt not being able to go through our proxy. As I understand the debootstrap doesnt have config file neither takes arguments on command line (relating to proxy), so I set following two environment variables:</p>
  
  <pre><code>ftp_proxy=http://myname:mypasswd@proxy.bla.bla.com:4128
  http_proxy=http://myname:mypasswd@proxy.bla.bla.com:4128
  </code></pre>
  
  <p>Still I am getting:</p>
  
  <pre><code># /usr/sbin/debootstrap --arch i386 wheezy /mnt/debinst http://ftp.cz.debian.org/debian
  I: Retrieving Release
  E: Failed getting release file http://ftp.cz.debian.org/debian/dists/wheezy/Release
  </code></pre>
  
  <p>the Release file can be get via browser, so it exists and so on...</p>
  
  <p>I wonder if this can be done at all</p>
  
  <p>Thanks</p>
