I'm marking this bug as Invalid. cloud-init is working as expected for
NoCloud datasource. Changes to the network-config during execution
can't affect cloud-inits behavior during boot with the NoCloud
datasource.

Title:
Update Ubuntu 20.04 default network-config by cloud-config
Status in cloud-init:
Invalid
Bug description:
This is a follow-up on the case https://bugs.launchpad.net/cloud-
init/+bug/1924922
I cannot update default Ubuntu network-config by writing user-data
file in cloud-config.
Attached are logs. Below is a snippet from the cloud-config
#cloud-config
write_files:
- path: /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
permissions: '0644'
content: |
network:
config: disabled
- path: /etc/netplan/50-cloud-init.yaml
permissions: '0644'
content: |
network:
version: 2
ethernets:
eth0:
dhcp4: true
addresses:
- 192.168.53.3/26
gateway4: 192.168.53.62
nameservers:
addresses:
- 1.1.1.1
- 8.8.8.8
runcmd:
- [sudo, netplan, try]
- [sudo, netplan, generate]
- [sudo, netplan, apply]
power_state:
mode: 'reboot'
message: 'reboot triggered by cloud-init'
-----
Result is such that the hardcoded network-config ('optional': True, not
waiting for DHCP server) is attached/generated with IP as, for an example -
192.168.53.4, not the IP I really want 192.168.53.3. This leads to couple of
problems, one as specified in bug/1924922, that ssh_import_id is not working
(for the time is not sync up)
Is there a way to overwrite this default with user-data, and not to go to the
config partition and manually change it?
