I agree that the /usr/lib/NetworkManager/conf.d/10-globally-managed- devices.conf should be deleted from Ubuntu's network-manager package.
Especially, as it is being overwritten in any normal Ubuntu Desktop installation, using the following netplan YAML: ``` network: version: 2 renderer: NetworkManager ``` If we use a global "renderer: NetworkManager" stanza (as is the default on Ubuntu Desktop, where NM is part of the default installation) netplan will create an empty file in /run/NetworkManager/conf.d/10-globally- managed-devices.conf, to override that file anyway. But we should be aware that it could introduce a change of default behavior on Ubuntu server where network-manager is being installed additionally. But netplan generates /run/NetworkManager/conf.d/netplan.conf to specifically ignore devices that are not supposed to be handled by NM, so we should be fine there, too. I've recently updated the allow- and deny-list logic in netplan to be more generic and instruct NetworkManager to ignore/manage devices based on specific udev rules. With this PR I'm also changing the 10-globally- managed-devices.conf logic to override Ubuntu's default anytime a NetworkManager interface is being defined in netplan YAML (not just if it's defined as the global renderer). https://github.com/canonical/netplan/pull/276 ** Changed in: netplan.io (Ubuntu) Assignee: (unassigned) => Lukas Märdian (slyon) ** Changed in: netplan.io (Ubuntu) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1951653 Title: can't use NM for ethernet device on 20.04 LTS because it is 'strictly unmanaged' Status in netplan.io package in Ubuntu: In Progress Status in network-manager package in Ubuntu: Confirmed Bug description: I have tried to tell netplan to let my ethernet device be managed by NetworkManager, so that I can then configure a pppoe connection on top of this device. This fails with: # nmcli c up netplan-wan Error: Connection activation failed: No suitable device found for this connection (device lo not available because device is strictly unmanaged). # I don't know why it mentions 'lo' in that message, but the wan interface is unmanaged (as are all devices on the system, but this one is supposed to be managed): # nmcli d status | grep wan wan ethernet unmanaged -- # After much searching, I've figured out that this comes from /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf: keyfile] unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma Even though I've told netplan to use the NM renderer for this device, the configuration emitted by netplan is insufficient to override this. Using the workaround from https://askubuntu.com/questions/71159/network-manager-says-device-not- managed (sudo touch /etc/NetworkManager/conf.d/10-globally-managed- devices.conf) doesn't work, but if I set NetworkManager as the toplevel renderer in /etc/netplan, /run/NetworkManager/conf.d/10-globally-managed-devices.conf is emitted, which evidently DOES work. But I only have one device that I want rendered by NM, so I shouldn't have to declare NM at the top level of the yaml with a lot of duplication in order to get this result. I would argue that the 10-globally-managed-devices.conf should not be there at all. But if it is going to be, then netplan needs to consistently override it whenever there is any use of the NetworkManager backend.
