Comment 3 for bug 2063813

You can reproduce this by running `cloud-init schema --system` in the debug shell. As you will see there, it finds that the network-config.json is invalid (so the cloud-config.txt is valid!)

The server iso [1] uses subiquity version 24.04.1, which has cloud-init 23.4.4-0ubuntu0~22.04.1 built in.

The fix for the issue you're observering is in cloud-init 24.1.1 or higher [2], as that contains the fix for this issue [3].

Refreshing the installer via a directive in your autoinstall.yaml wouldn't help, because the schema is invalid, so it doesn't get there...

```
refresh-installer:
  update: true
  channel: latest/edge
```

... however, one could run `snap refresh subiquity --channel=latest/edge` by hand at the shell prompt after the error occurs. From there, the install will continue to run.
