dbus-daemon 1.14.0-2ubuntu2 (armhf binary) in ubuntu lunar

 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 contains dbus-daemon, the reference implementation of a
 D-Bus message bus, and dbus-run-session, a utility to start a temporary
 session dbus-daemon in a constrained environment or for automated tests.
 .
 To provide a complete D-Bus session bus, install one of the packages
 that implement the dbus-session-bus virtual package, such as
 dbus-user-session. The recommended implementation is indicated by
 the default-dbus-session-bus virtual package.
