Looking in the code: [1] In netplan.py(https://github.com/cloud-init/cloud-init/blob/6d48d265a0548a2dc23e587f2a335d4e38e8db90/cloudinit/net/netplan.py) ``` def _render_content(self, network_state): # if content already in netplan format, pass it back if network_state.version == 2: # <==== we got None here ``` seems like network_state is None. Let's see where this is set. [2] It is set in renderer.py (https://github.com/cloud-init/cloud-init/blob/6d48d265a0548a2dc23e587f2a335d4e38e8db90/cloudinit/net/renderer.py) ``` network_state=parse_net_config_data(network_config), target=target) ``` [3] Looking at parse_net_config_data() in network_state.py (https://github.com/cloud-init/cloud-init/blob/6d48d265a0548a2dc23e587f2a335d4e38e8db90/cloudinit/net/network_state.py) ``` def parse_net_config_data(net_config, skip_broken=True): """Parses the config, returns NetworkState object :param net_config: curtin network config dict """ state = None version = net_config.get('version') config = net_config.get('config') if version == 2: # v2 does not have explicit 'config' key so we # pass the whole net-config as-is config = net_config if version and config: nsi = NetworkStateInterpreter(version=version, config=config) nsi.parse_config(skip_broken=skip_broken) state = nsi.get_network_state() # <====== here return state ``` >From the same file, in the class NetworkStateInterpreter(): ``` def get_network_state(self): ns = self.network_state return ns ``` Then looking into where is self.network_state populated, I can't find any other reference to it, which would explain why it is always None. Probably the mistake here is that this is mistyped (should be self._network_state). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686338 Title: cloud-init fails if no network config is set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1686338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
