We want to implement an explicit allow- and denylist for NM to handle
certain device (or not). NM’s own matching engine is not powerful enough
to handle all of netplan’s matching needs, but it can also be
implemented with udev matching rules, using ENV{NM_UNMANAGED}="1"We also want to discuss with the desktop team if we really need/want /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf (this is a change in Ubuntu's default behavior) -- 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: Triaged Status in network-manager package in Ubuntu: New 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.
