gir1.2-mate-desktop 1.19.3-0ubuntu2 (arm64 binary) in ubuntu bionic

 The MATE component mate-desktop contains the libmate-desktop library, the
 mate-about program, as well as some desktop-wide documents.
 .
 The libmate-desktop library provides an API shared by several applications
 on the desktop, but that cannot live in the platform for various
 reasons.
 .
 This package contains introspection data for the library.
 .
 It can be used by packages using the GIRepository format to generate
 dynamic bindings.
