TPM-backed Full Disk Encryption is coming to Ubuntu - Discussion

What do I need to do to make the FDE feature available in the installer on my HP EliteBook 840 G5?

I have done the following:

  1. Ensure Secure Boot is enabled.
  2. Ensure TPM is enabled.
  3. Wipe the SSD clean using Secure Erase from BIOS.
  4. Wipe the TPM clean (tried both from BIOS menu and using echo 5 | sudo tee /sys/class/tpm/tpm0/ppi/request + reboot + confirm wipe).

But the installer still won’t let me enable hardware-backed full disk encryption.
