Didn't know it was switching to py3 :-)
Indeed, installing python3-mako makes the previous error message go away. But the result is even worst now, as ifupdown2 completly fails and don't even configure interfaces which are not using templates in /etc/network/interfaces

So it looks like ifupdown2 v3 is not fully compatible with config working in v2. Haven't digged yet into it (those are prod servers, so not easy to play with their network stack)

Cheers,
Daniel
