[Bug 2107457] Re: Can't boot after installation with TPM backed FDE on xps9320

[Olivier Gayot]

Hello Mate, hello Chris,

I did another install and tried booting the target system from the exact
same menu but it still asked me for the recovery key.

Quickly after powering on the laptop, I hit F12 - "One-Time Boot
Settings" then select the USB media if I want to boot the installer - or
select the NVMe drive if I want to boot the target system.

I will attach some screenshots, along with:

* the measurements file (collected when booting the installer for the first time)
* the measurements file (collected after failing to boot the target system - and booting the installer again)

Some details that I assume are not relevant:

* The ISO was dd-ed onto the USB drive (i.e., dd if=plucky-desktop-amd64.iso of=/dev/sda bs=1M conv=sync)
* The USB drive is connected to the laptop using a USB3 to USB-C adapter.

Title:
  Can't boot after installation with TPM backed FDE on xps9320

Status in subiquity package in Ubuntu:
  New

Bug description:
  I tried installing Ubuntu 25.04 desktop with TPM backed FDE on two
  different XPS 9320 units.

  The installation seems to succeed.

  However, on first boot, it is asking me for a recovery key.

  Please enter the recovery key for volume ubuntu-
  data-a2b3ba2e-2555-4957-a47b-94804d4c119 for device /dev/disk/by-
  uuid/6bdc5a11-5d7d-4d64-89f-05d9464191e (press TAB for no echo)

  Inputting the passphrase entered during the installation does not work
