Public bug reported:

Operating System: Ubuntu 24.04.3 LTS              
Kernel: Linux 6.14.0-29-generic
Architecture: x86-64

Reproduction:
- create system from current noble-server-cloudimg-amd64.img
- expose a cloudinit configuration for network-config
- Apply any pending updates `apt-get update && apt-get full-upgrade`
- Install Ubuntu-desktop with no recommends switch `apt-get install --no-install-recommends ubuntu-desktop`
- Reboot system `sudo reboot now`

Suspected Causation:
- cloud-init detects netplan and renders network configuration in /etc/netplan/50-cloud-init.yaml, this network configuration does not include a renderer section.
- NetworkManager is not marked as required for Ubuntu-Desktop or Ubuntu-Settings
- ubunut-settings package creates file /usr/lib/netplan/00-network-manager-all.yaml, this file includes a renderer section, configured to NetworkManager
- on reboot netplan merges 50-cloud-init.yaml and 00-network-manager-all.yaml resulting in renderer: NetworkManager
- as network manager is not installed netplan throws an error when loading the network configuration.

Workaround:
- persists after install and update
sudo dpkg-divert --divert /usr/lib/netplan/00-network-manager-all.yaml.diverted --rename /usr/lib/netplan/00-network-manager-all.yaml

- non-persistant
sudo mv /usr/lib/netplan/00-network-manager-all.yaml /usr/lib/netplan/00-network-manager-all.yaml.diverted 
sudo netplan generate
sudo netplan apply


I suspect that this could be fixed either by Ubuntu-Settings detecting which network renderer is installed, or by modifying the distribution specific cloud-init configuration or netplan renderer.
