Public bug reported:

I am trying to create a Ubuntu 18.04 VM using Openstack solution, I want
to assign IPv6 to the VM and I have disabled DHCP in the IPv6 subnet. It
is noticed that cloud-init is able to read the network related
information from the metadata url but not using it to assign it to the
VM.

I noticed that it is not updating the /etc/netplan/50-cloud-init.yaml
file with proper configuration.

Cloud-Init version being used is 20.2 "/usr/bin/cloud-init
20.2-45-g5f7825e2-0ubuntu1~18.04.1".

I am attaching the cloud-init logs for the reference.

Below is the Rest API Output for network info
root@test-ubuntu-18:~# curl http://169.254.169.254/openstack/latest/network_data.json
{"services": [{"type": "dns", "address": "8.8.8.8"}, {"type": "dns", "address": "2001:4860:4860::8888"}], "networks": [{"network_id": "511****a166-7f3e-432e-bbf3-c006ccc4fb78", "link": "tap7422d0eb-8a", "type": "ipv4_dhcp", "id": "network0"}, {"network_id": "511****7f3e-432e-bbf3-c006ccc4fb78", "type": "ipv6", "services": [{"type": "dns", "address": "2001:4860:4860::8888"}], "netmask": "ffff:ffff:ffff:ffff::", "link": "tap7422d0eb-8a", "routes": [{"netmask": "::", "network": "::", "gateway": "2***:****:****:****::1"}], "ip_address": "2***:****:****:****::13f", "id": "network1"}], "links": [{"ethernet_mac_address": "fa:16:3e:16:09:37", "mtu": 1500, "type": "bridge", "id": "tap7422d0eb-8a", "vif_id": "7422d0eb-8aa5-4310-859c-8f60456045d9"}]}

Things are working well with Ubuntu 20.04. I am not sure, what am I
missing here.
