Issue
In a freshly installed and updated LMDE3 the privacy settings module will not open.

Steps to reproduce

Attempt to lauch the privacy settings module by any method.

If run from the terminal the following output is produced.

Steve@lmde3-vm:~$ cinnamon-settings privacy
True
Using pam module (python3-pampy)
Loading Privacy module
Traceback (most recent call last):

    self.go_to_sidepage(cat, path, user_action=False)

    if nm_client is not None and nm_client.connectivity_check_get_available():
AttributeError: 'Client' object has no attribute 'connectivity_check_get_available'

As LMDE3 out of the box does not have network-manager-config-connectivity-debian available, I tried adding stretch backports, updating network-manager from stretch-backports and installing network-manager-config-connectivity-debian. However this did not resolve the issue.

Expected behaviour

Privacy settings module should work in LMDE3
