lsb-desktop 4.0-0ubuntu6 (ia64 binary) in ubuntu lucid

 The Linux Standard Base (http://www.linuxbase.org/) is a standard
 core system that third-party applications written for Linux can
 depend upon.
 .
 This package provides an implementation of version 4.0 of the Linux
 Standard Base Desktop specification for Debian on the Intel x86,
 Intel ia64 (Itanium), IBM S390, and PowerPC 32-bit architectures with
 the Linux kernel. Future revisions of the specification and this
 package may support the LSB on additional architectures and kernels.
 .
 The intent of this package is to provide a best current practice way
 of installing and running LSB packages on Debian GNU/Linux. Its
 presence does not imply that Debian fully complies with the Linux
 Standard Base, and should not be construed as a statement that Debian
 is LSB-compliant.
