Comment 12 for bug 1902425

Based on the patches, it seems, this got landed, and based on the snap version, I should have this fix.

I have deployed a brand new MAAS server (lab environment), and set all the interfaces of all my VMs to Auto-Assign (except for the external interface), but I am unable to deploy any VMs or machines through MAAS. I have the snap installed and using the maas-test-db. When I set the intrefaces to grab IP from DHCP, then MAAS successfully gives the IP via that method. Is there anything I am missing?

nap list | grep maas

maas-cli 0.6.5 16 latest/stable canonical* -
