Describe the bug
Using a ThinkPad X1 Carbon 6th Gen running Ubuntu 20.04.

After replacing the Absolute Persistence Module version (UEFI BIOS ID N23ET73W) with the Non-Absolute Persistence Module version (UEFI BIOS ID N23ET73P) — remove Anti-Theft > Computrace — fwupdmgr get-devices shows "TPM PCR0 differs from reconstruction" error for the System Firmware.

Due to this update, the System firmware Device ID had changed from 1c53551e7da69d896138fac1ae131c83ad46d923 to 2c7a30f46dc2054be78c13cfaba2dc3ba2fee2b0 . So actually the error message is correct, but nothing else is reporting the TPM PCR0 differencies.

replacing the Absolute Persistence Module version (UEFI BIOS ID N23ET73W) with the Non-Absolute Persistence Module version (UEFI BIOS ID N23ET73P)

I think that's a very much unsupported system; if you use the standard non-modified image does the TPM event log reconstruct correctly?

That probably should work, but as far as I know, the update isn't reversible — I will try that later.

You can only install the P-Update — which removes Computrace and the Anti-Theft menu completely — if you disable Computrace in BIOS, so it could not be enabled again. If you then do a BIOS upgrade — at least booting the ISO — the P-Update is installed, and it is also available via fwupd.

The culprit is the changed Device ID, but I don't know — and understand completely — how fwupd is reporting the PCR0 mismatch or if it is completely relying on the TPM. If the latter is the case, it's not a bug.

Thing is, PCR0 Type 0x8 EV_S_CRTM_VERSION contains the actual BIOS ID, which change with every update and the FIRMWARE_BLOBs should change to. Ahm, I should have run a fwupdtpmevlog before the update. It was a reinstall of 1.48, just from Absolute to Non-Absolute.

After installing System Firmware 1.49 the error disappeared.

Apologies for the off-topic.

@renffah Could you please clarify how did you manage to install the P-firmware in the first place? Is it possible to do via fwupd?

It's a long time ago.
Downloaded the P firmware (afair a cab archive or extracted from the iso) and installed it, (free)dos or fwupdmgr.
Maybe I have it documented somewhere, but the X1 and me are in different places right now.
