title: Archive repository for Debian Squeeze
body: <p>I still use Debian Squeeze, and since this release has been archived (Feb 29, 2016) I use the archives repositories on archive.debian.org</p>
  
  <pre><code>deb http://archive.debian.org/debian-archive/debian/ squeeze main contrib non-free
  deb http://archive.debian.org/debian-archive/debian/ squeeze-lts main contrib non-free
  </code></pre>
  
  <p>Since 2 days , I get this error message with aptitude update: (same with apt-get)</p>
  
  <pre><code>E: Release file expired, ignoring http://archive.debian.org/debian/dists/squeeze-lts/Release (invalid since 2d 17h 24                                                                                                                        min 57s)
  </code></pre>
  
  <p>With increasing time of course. I tried many other archives repositories but same error.
  I found this workaround:</p>
  
  <pre><code>aptitude -o Acquire::Check-Valid-Until=false update
  </code></pre>
  
  <p>It works, but I would find a solution without this option. I have no fast possibility to update aptitude parameters on all servers I'm running.</p>
  
  <p>By the way the question is: what is the problem with repositories ? Am I doing something wrong ?</p>
  
  <p>I found no update or news about repositories problem on Debian site/mailing list.</p>
