I was struggling with this for quite some time and played around using netplan.io and not using it. I figured out that you need to run "update- initramfs -u" to make settings persist reboots in "/etc/systemd/network/" when not using netplan.io.
But netplan.io saves the configuration in "/run/systemd/network/". Here the update of initramfs does not make any difference and on boot the network set-up fails to rename the interfaces as configured with all consequences for the system. To me it appears that "update-initramfs" needs to include the generated configuration from netplan.io to get the network configuration correct on reboot. The following workaround does the job for me after every configuration change in netplan.io: 1. netplan apply 2. rm /etc/systemd/network/10-netplan-*.link 3. cp /run/systemd/network/10-netplan-*.link /etc/systemd/network/ 4. update-initramfs -u Now the generated link files are found by update-initrd. Never the less there should be a consistent solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770082 Title: systemd-networkd not renaming devices on boot To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1770082/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
