Thanks for the author!
On Debian 12 I got couple of issues when I ran netplan try. I'll share my solutions:
- "Cannot call Open vSwitch: ovsdb-server.service is not running."
apt-get install openvswitch-switch
https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/2041727
- "gateway4 has been deprecated, use default routes instead."
replaced:
gateway4: 192.168.10.1
with:
routes:
- to: default
via: 192.168.10.1

- My /etc/resolv.conf was emptied by NetworkManager somehow when turning WiFi off, so my eth0 wasn't resolving hostnames.
apt install systemd-resolved

Thank you, this helped a lot! I never would have remembered to do that last symlink!
It's really strange but I could not find any official documentation for the
netplan migratecommand. It used a couple of depreciated things likegateway4but overall it worked really well!A couple of things I discovered it does:
/etc/network/interfacesto generate a netplan config file named/etc/netplan/10-ifupdown.yaml/etc/network/interfacesto/etc/network/interfaces.netplan-convertedNote sure if it does anything else, those are just the things I noticed.
