title: apt-get update Bad header line
body: <p>I'm hosting a reprepo debian package server with a bunch of arm packages for an embedded linux project. I have arm symbol files in the repo. On my host machine, Ubuntu 14.04 LTS, I want to -force-architecture install them. When I update my PPAs with my debian repo <code>apt-get update</code> is erroring with <code>Bad header line</code>. I've been searching for hours for a solution. Can't even find a way to turn on verbose for apt-get. dpkg has --debug= so I tried <code>sudo apt-get -o Dpkg::Options::="--debug=3773" update</code> with no success.</p>
  
  <p>Checked /var/log/dpkg.log and /etc/apt/*.logs nothing in them... How do you debug apt-get?</p>
