Hi, I want to delete connections using a snap that uses network-manager plug . So i tried
#!/usr/bin/env python3 import dbus, uuid
bus = dbus.SystemBus() proxy = bus.get_object(“org.freedesktop.NetworkManager”, “/org/freedesktop/NetworkManager/Settings”) settings = dbus.Interface(proxy, “org.freedesktop.NetworkManager.Settings”)
connection_paths = settings.ListConnections()
for path in connection_paths: con_proxy = bus.get_object(“org.freedesktop.NetworkManager”, path) settings_connection = dbus.Interface(con_proxy, “org.freedesktop.NetworkManager.Settings.Connection”) config = settings_connection.GetSettings() if (config[“connection”][“type”] == “wireguard”): print("Deleting connection " + config[“connection”][“id”]) settings_connection.Delete()
But it always gives an app armor permission denied error.
