lsb-release 12.0-2 (i386 binary) in ubuntu mantic

 The Linux Standard Base (http://www.linuxbase.org/) is a standard
 core system that third-party applications written for Linux can
 depend upon.
 .
 The lsb_release command is a simple tool to help identify the Linux
 distribution being used and its compliance with the Linux Standard Base.
 .
 This package contains a bare-bones implementation that uses the
 information in /etc/os-release instead of relying on LSB packages.
