title: How to install apt package in debian?
body: <p>I am having Debian GNU/Linux 6.0.4 (squeeze). By mistake all the apt files are removed from my OS. I am trying to install package "apt_0.9.7.1_amd64.deb". But while installing the package i am getting the following errors :</p>
  
  <pre><code>Unpacking replacement apt ...
  dpkg: dependency problems prevent configuration of apt:
   apt depends on libapt-pkg4.12 (&gt;= 0.9.7.1); however:
    Package libapt-pkg4.12 is not installed.
   apt depends on libstdc++6 (&gt;= 4.6); however:
    Version of libstdc++6 on system is 4.4.5-8.
   apt depends on debian-archive-keyring; however:
    Package debian-archive-keyring is not installed.
  dpkg: error processing apt (--install):
   dependency problems - leaving unconfigured
  Processing triggers for man-db ...
  Errors were encountered while processing:
   apt
  </code></pre>
  
  <p>Can anyone know how to install the apt package? or are there any other ways to install the package.</p>
  
  <p>While using any command like sudo apt-get update etc. I am getting error</p>
  
  <pre><code>apt : Depends: debian-archive-keyring but it is not going to be installed
  </code></pre>
  
  <p>For installing debian-archive-keyring I need apt and for apt I need debian-archive-keyring.
  Please suggest any solution.</p>
