lsb-core 10.2019031300ubuntu1 (i386 binary) in ubuntu disco

 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 the core of the Linux Standard
 Base 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.
