installation issue - vlan interface not defined[ #678
Description
I am encountering an error while trying to configure a VLAN using netplan. The specific issue is in the file /etc/netplan/00-vlan.yaml.
To Reproduce:
Edit the file /etc/netplan/00-vlan.yaml with a text editor.
Attempt to define a VLAN (e.g., VLAN 10) with a specific interface name (e.g., ens2) in the link: option.
Save the changes and run the command sudo netplan apply.
Observe the following error message:
/etc/netplan/00-vlan.yaml:9:13: Error in network definition: vlan10: interface 'ens2' is not defined
Expected Behavior:
The netplan configuration should be applied successfully, and the specified VLAN should be created using the designated interface.
Environment:
OS: [Specify your Operating System - e.g., Ubuntu 22.04]
Kernel Version: [You can find this by running uname -r in your terminal]
Additional Context:
I have verified that the interface name mentioned in the error message (ens2 in this example) might not be the actual interface name. I used the ip addr command to list network interfaces and identify potential candidates (e.g., enpXsY).
I've also checked the file permissions for /etc/netplan/00-vlan.yaml to ensure they are appropriate (ideally owner-writable only).
