dbus-1-dbg 1.10.4-1ubuntu2 (powerpc binary) in ubuntu xenial

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides support for debugging programs that use the core
 D-Bus shared library.

 See the dbus package description for more information about D-Bus in general.
