lsb binary package in Ubuntu Focal amd64

 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 only the printing and core
 modules of the Linux Standard Base for Ubuntu. Recent versions of Ubuntu
 do not implement the full LSB interfaces; this package is provided only for
 compatibility with third-party printer driver packages which depend on the
 lsb package.
 .
 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 Ubuntu fully complies with the Linux Standard Base,
 and should not be construed as a statement that Ubuntu is LSB-compliant.
