Thank you! The core problem still is that systemd-networkd does not find any .link and .network file for the enP53p0s0.171 interface, that's why it cannot apply any configuration (IP address):
> ? 9: enP53p0s0.171 > Link File: n/a > Network File: n/a This might very well be related to the additional /etc/systemd/network/10-enP53p0s0.link, which is now gone and apparently not needed (good!) – leave that away. Still the configuration/match of that file might still be loaded into the running udev, so we must somehow reset udev to a clean state. I'd like to ask you for another test run (and potential reboot of that machine – if that is possible?): # try to reload udev at runtime udevadm control --reload; udevadm trigger; udevadm settle # wait a bit sleep 30 # apply netplan configuration netplan --debug apply # wait a bit sleep 30 # check results networkctl status enP53p0s0.171 --no-pager ip a If the IP is still not set, could you please try to reboot the machine and check "networkctl" afterwards? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1929657 Title: [Ubuntu 20.4.2] vLan not getting static IP assigned (on s390x) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1929657/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
