netplan error: gateway6 has been deprecated with latest ubuntu 20.04 image

[landorg]

Hi. I'm ending up here with:

[18:10:19] fatal: netplan generate stderr not empty:
[18:10:19] :
[18:10:19] :   ** (generate:3): WARNING **: 18:10:19.467: `gateway6` has been deprecated, use default routes instead.
[18:10:19] :   See the 'Default routes' section of the documentation for more details.
[18:10:19] => FAILED

using the most recent 20.04 ubuntu image.

Maybe this needs to be updated to:

    [[ "$IAM" == ubuntu ]] && ((IMG_VERSION < 2004)) && force_pre_103_style=1

Using this image: https://releases.ubuntu.com/jammy/ubuntu-22.04.3-live-server-amd64.iso

Any idea how to work around this? Thanks

Installimage works with tar archives. It does not support ISO images. For custom images you can find the requirements here: https://docs.hetzner.com/robot/dedicated-server/operating-systems/installing-custom-images/#install-older-linux-images-using-the-installimage-script
