Title:
  TPMFDE installation fails for autoinstall

Status in snapd:
  New
Status in ubuntu-desktop-installer:
  New
Status in subiquity package in Ubuntu:
  Incomplete

Bug description:
  When installing Ubuntu 23.10.1 using the new ubuntu-desktop-installer with an autoinstall config and TPMFDE storage layout, the installation completes successfully but upon reboot is unable to unlock the disk.
  Note this is the FIXED ISO (16/10/2023) after the earlier issue with malicious translations.

  Instead I am prompted for the recovery key, which I am unable to
  acquire before rebooting into the newly installed system

  Below is the autoinstall config used

  ```
  #cloud-config
  autoinstall:
    version: 1
    interactive-sections:
      - keyboard
      - network
    locale: en_GB.UTF-8
    keyboard:
      layout: gb
    kernel:
      flavor: generic
    apt:
      geoip: true
      preserve_sources_list: false
      primary:
        - arches: [default]
          uri: 'http://archive.ubuntu.com/ubuntu'
    identity:
      hostname: unassigned-hostname
      username: redacted
      realname: redacted
      password: 'redacted'
    ssh:
      install-server: true
      authorized-keys: []
      allow-pw: true
    storage:
      grub:
        reorder_uefi: false
      layout:
