LEAdvertisingManager1 is missing from DBus.ObjectManager.GetManagedObjects

Question

I run tests with my home computer running Ubuntu and Python 2.7 in the hope that the Raspberry Pi 3 advertises the use of BLE with user services and features. I installed Bluez version 5.42 (using the recommended method) on both devices, as well as on dbus-python. My computer and Raspberry Pi can advertise using the command hci0 lescan 0, but I would like to advertise the bluez example scripts, example-gatt-client.py and example-advertisement.py found here , since I want to use my own custom characteristics.

Home computer - kernel version 4.4.0-31 general

I can create custom features and ads by running example-gatt-server.py and example-advertise.py without any problems on my home computer. The only thing I had was that I needed to turn on the Bluez experiment mode by adding --experimentalto the bluetooth.service file located at /lib/systemd/system/bluetooth.service. In addition, installing the dbus-python library was a bit painful since I had to install it myself and install it for Python2.

The script commercial is looking for a specific advertising interface called "org.bluez.LEAdvertisingManager1". The gatt-server.py script is looking for "org.bluez.GattManager1". I can check if this interface exists by running the following command:

dbus-send --system --dest=org.bluez --print-reply / org.freedesktop.DBus.ObjectManager.GetManagedObjects

These interfaces are found and work fine on my home computer. Scripts run without problems.
