Title:
  edubuntu-installer and ubuntustudio-installer incorrectly report
  package as installed when using languages other than English

Status in edubuntu-installer package in Ubuntu:
  Fix Released
Status in ubuntustudio-installer package in Ubuntu:
  Fix Released

Bug description:
  Both edubuntu-installer and ubuntustudio-installer are using the
  following code to determine if a package is installed:

  apt-cache policy "${pkg}" | grep Installed | cut -d ':' -f 2 | cut -c
  2-

  This relies on the string "Installed" being returned by apt-cache
  which is translated depending on the system language. Since neither
  edubuntu-installer nor ubuntustudio-installer are localized as of now,
  another route for determining package installation needs to be used.

  This will likely be doable by using the error code return from

  dpkg -s "${pkg}" &> /dev/null

  Additionally, some other idiosyncrasies were used when looking for
  Depends and Recommends. Now a different algorithm will be used without
  depending on specific words.
