Howto deploy latest netplan main on 20.04 LTS?
np flag

Well, title says mostly all. I have a problem with netplan as it is distributed with current 20.04.3 (#102) and even #103 which is in proposed is not good enough. New "ignore-carrier" option which is kind of new seems to fit the bill, but it is not obvious to me how to deploy current neplan.io "main".

Help ?

how to set static IP address on ubuntu server? netplan apply command ignored

Netplan and Ipsec - tell netplan to leave interface alone?

I'm trying to use Strongswan to create an Ipsec tunnel on a server with Netplan. Netplan has currently no configuration for the tunnel1 and tunnel2 interfaces that Ipsec brings up when the tunnels are created. This seems (almost) correct to me.
