- The signature of this function changed, it's now (uass)
- GDBus is the future.

Here is a simple, not error safe, port to GDBus, but using the sync API makes me cry.


  xid = GDK_WINDOW_XID (gtk_widget_get_window (dialog));

  proxy = g_dbus_proxy_new_for_bus_sync (G_BUS_TYPE_SESSION,
      G_DBUS_PROXY_FLAGS_NONE, NULL,
      "org.freedesktop.PackageKit",
      "/org/freedesktop/PackageKit",
      "org.freedesktop.PackageKit.Modify",
      NULL, &error);
  g_assert_no_error (error);

  g_dbus_proxy_call_sync (proxy, "InstallPackageNames",
      g_variant_new ("(u^a&ss)", xid, packages, ""),
      G_DBUS_CALL_FLAGS_NONE, -1, NULL, &error);
  g_assert_no_error (error);
