Unable to create VLAN for a bridge interface

Hello,

I was trying to mitigate the current disability of the compose plugin to create a vlan and decided to go with a more generic approach.

I currently have a bridge interface br0. When i try to create a vlan with a parent interface set to br0 a got a error

[ERROR ] Command 'netplan' failed with return code: 78

[ERROR ] stderr: /etc/netplan/50-openmediavault-br0.10.yaml:11:13: Error in network definition: br0.10: interface 'br0' is not defined

link: br0

^

[ERROR ] retcode: 78

[ERROR ] {'pid': 909210, 'retcode': 78, 'stdout': '', 'stderr': "/etc/netplan/50-openmediavault-br0.10.yaml:11:13: Error in network definition: br0.10: interface 'br0' is not defined\n link: br0\n ^"} in /usr/share/php/openmediavault/system/process.inc:247

Attached is the entire re-configuration log

As simple as that. Works perfectly in compoose plugin. I got my containers up and running finally. Thank you for your effort

However have not tested the VLAN creation in the Network->Interfaces which was the root reason of this post
