  but each time i try to do the command <code>sudo apt-get install ubuntu-desktop</code><BR/>
  this error shows up:<BR/><BR/></p>
  
  <pre><code>Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/libp/libproxy/
  libproxy0-o.3.1-ubuntu1-amd64.deb 403 Forbidden [Ip:91.189.92.179 80]
  
  E:ubable to fetch some archives,maybe run apt-get update or try with fix --missing?
  </code></pre>

  <BR/>
  I tried <code>fix missing</code> command but didn't work for the same reason.
  I tried to cahnge the proxy like this:<BR/></p>
  
  <ol>
  <li>changed the proxy in my host computer. (ultra serf)</li>
  <li>changed the proxy settings in my VM to Bridged And Riplicate physical network Connection<BR/> state.</li>
  <li><p>run the command:<BR/></p>
  
  <p>export http-proxy<BR/>
  http-proxy=http://127.0.0.1:80 <BR/><BR/>
  same problem, so mybe i should change the proxy settings in ubuntu but I don't know how<BR/><BR/><BR/> By the way the missing file that is refusing to be downlaoded is <code>38.1KB</code> and all other files are perfectly downloaded<BR/>
  so maybe i can just download it in the host(windows xp) and move to ubuntu<BR/> but i don't know where is the directory for the downloaded package <code>OR</code> where can i add this file, can any one help me?</p></li>
