Description
ThinkPad X1 Carbon 8th Gen — TPM‑FDE Fails During Ubuntu Installation
When selecting tpm-fde in the Ubuntu installer, the process fails with the following message:
Hardware-backed encryption could not be enabled.
This computer does not have the required security hardware (TPM 2.0)
for this encryption method.
Contact IT support.
Technical details:
NO_SUITABLE_TPM2_DEVICE
Error with TPM2 device: cannot check TPM discreteness using Intel BootGuard status:
no TPM2 device is available.
I have a discrete TPM, and TPM‑FDE worked perfectly on previous Ubuntu 24.04 releases.
