title: FreeBSD pkg repository not updating and thinks it is up to date
body: <p>I was installing a package using pkg and cancelled during the update check phase. I think this bugged it and now when I run pkg update it says it is on the latest versions. However, it most definitely is not.</p>
  
  <p>Is there a way to force a clean repo list to pull the latest version info?</p>
  
  <p>This is the error when I try to install php56 for example:</p>
  
  <pre><code>username@shavedbox:/usr/home/username # pkg install php56
  Updating FreeBSD repository catalogue...
  FreeBSD repository is up-to-date.
  All repositories are up-to-date.
  The following 1 packages will be affected (of 0 checked):
  
  New packages to be INSTALLED:
          php56: 5.6.6
  
  The process will require 15 MiB more space.
  2 MiB to be downloaded.
  
  Proceed with this action? [y/N]: y
  pkg: http://pkg.FreeBSD.org/FreeBSD:10:amd64/latest/All/php56-5.6.6.txz: Not Found
  </code></pre>
  
  <p>(The most recent version is 5.6.7 so the file is obviously not found)</p>
  
  <p>Any help is greatly appreciated! Not too used to FreeBSD...</p>
