python-dbus-dev 1.2.6-1 (s390x binary) in ubuntu bionic

 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 development files required to compile main-loop
 integration modules for python-dbus, such as dbus.mainloop.pyqt5 provided
 by PyQt. It is Python-version-independent: packages that build-depend
 on python-dbus-dev should also build-depend on python-dbus,
 python3-dbus, python-dbus-dbg and/or python3-dbus-dbg.
