Public bug reported: 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. ** Affects: netplan.io (Ubuntu) Importance: High Status: New ** Affects: network-manager (Ubuntu) Importance: High Status: New ** Also affects: netplan.io (Ubuntu) Importance: Undecided Status: New ** Changed in: netplan.io (Ubuntu) Importance: Undecided => High ** Changed in: network-manager (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951653 Title: can't use NM for ethernet device on 20.04 LTS because it is 'strictly unmanaged' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1951653/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
