Matt, This is expected behavior. MAAS provides network configuration to cloud-init (via curtin). Cloud-init will rename interfaces that are part of the provided network configuration to ensure the configuration will apply. If you need to reconfigure or provide additional configuration, you have a couple options.
1) You could modify the 50-curtin-networking.cfg with your desired changes 2) You can disable cloud-init networking and provide your own in /etc/netplan % cat /etc/cloud/cloud.cfg.d/50-curtin-networking.cfg network: config: disabled ** Changed in: cloud-init (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773397 Title: cloud-init renames interfaces at every boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1773397/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
