[Bug 2041480] [NEW] Netplan 0.106.1-7ubuntu0.22.04.2 breaks mac address match

[Alan Baghumian]

Public bug reported:

Hello There!

This is a rather important issue and is currently affecting many Jammy
machines / containers that contain mac address match line in the netplan
file. An example:

network:
  version: 2
  ethernets:
    eth0:
      match:
        macaddress: 00:16:3e:06:05:12
      addresses:
      - 10.1.15.188/21
      gateway4: 10.1.10.1
      nameservers:
        search: [alannet]
        addresses: [10.1.9.6, 10.1.9.12, 10.1.10.10]


We noticed after upgrading netplan from 0.105-0ubuntu2~22.04.3 to 0.106.1-7ubuntu0.22.04.2 causes units to fail to bring IP addresses up.

There are currently two workarounds:

1. Remove the match line from the netplan yaml
2. Downgrade back to 0.105-0ubuntu2~22.04.3

This should be very easy to reproduce. I'm pasting the
0.105-0ubuntu2~22.04.3 package links here as well:

Please let me know if you'd like more logs or information.
