Hi,

I can't find anything wrong in your configuration. And that makes me wonder if you have another YAML with the same wg0 interface in it. We recently fixed a bug in Network Manager that was leading to duplication in the configuration. You might have been affected by this bug when you upgraded to Mantic.

If you grep /etc/netplan by the interface name, do you see more than one file? Something like this "sudo grep wg0 /etc/netplan/*". If you find the same interface in more than one file, try to remove them and create the connection again using the GUI. The problem might be that you have multiple YAMLs with the same interface. Netplan will merge them in a single configuration and the result might be a broken config.

Let me know if it helps.

Thanks!
