Title:
  apt-ftparchive on-disk cache format changed between lucid and precise,
  results in Packages files with silently corrupted checksums fields

Status in “apt” package in Ubuntu:
  Fix Released
Status in “apt” source package in Trusty:
  In Progress

Bug description:
  The archive.ubuntu.com master server has just been upgraded from lucid
  to precise.  As a result, the apt version went from 0.7.25.3 to
  0.8.16~exp12, and apparently some time in that interval the on-disk
  format of apt-ftparchive's cache changed.

  This wouldn't be a problem, except apt-ftparchive itself doesn't
  *notice* that the cache format has changed, and instead happily reads
  the existing files and parses them incorrectly, resulting in corrupted
  checksums output in the Packages file for each of the .debs.

  apt-ftparchive should version its file formats so that it correctly
  notices incompatible cache files.
