Title:
  Blank line in previously installed packagedescription causes 12.04
  upgrade failure

Status in dpkg:
  New
Status in “dpkg” package in Ubuntu:
  Triaged

Bug description:
  While attempting to upgrade from 11.10 to 12.04 the version of dpkg
  used by Ubuntu was upgraded.  The new version was unable to parse my
  /var/lib/dpkg/status and /var/lib/dpkg/available files.  Under 11.10,
  I had installed a package from Lexmark for a printer driver that had a
  blank line in the package description field.  The old version of dpkg
  was apparently able to parse the file with the blank line.  However,
  when the new version encountered the files.  any further package
  updates failed and the update process proceeded to the cleanup/reboot
  phase.

  My system was usable following the reboot, and I was able to find the
  blank lines and manually edit them to allow dpkg to start working
  again.  There were some broken packages as a result of the failed
  upgrade.  I was able to fix them using apt-get install -f.  I was then
  able to complete the upgrade with an apt-get dist-upgrade.

  There may need to be some checks added to the upgrade procedure to
  prevent upgrade failures when a package description has a blank line.
