I did some additional debugging on this and found the file `/run/NetworkManager/conf.d/netplan.conf` with contents: [keyfile] # devices managed by networkd unmanaged-devices+=interface-name:enp1s0
Removing that file leads to the device being listed as managed by `nmcli d status`, but this file get's created again every reboot by netplan, so it does not hold for long. (And then the device is unmanaged again) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876884 Title: eth connection 'unmanaged' when using netplan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1876884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
