This guide provides concise steps to check for TPM availability and install TPM TSS2 on an Ubuntu system (tested with Ubuntu 22.04 LTS).

1. Check for TPM Device

Ensure that a TPM device is available on your system:

ls /dev/tpm*

If /dev/tpm0 exists, a TPM device is present. If not, verify in your BIOS/UEFI settings that TPM is enabled.

2. Prepare the System

Update the system:

sudo apt update && sudo apt upgrade -y

3. Install TPM-TSS2 and TPM2 Tools

Install the TPM packages:

sudo apt install -y tpm2-tools

If you need the TPM resource manager daemon, install it with:

sudo apt install -y tpm2-abrmd

4. Enable the TPM Service

If you installed the TPM daemon, enable and start the service:

sudo systemctl enable tpm2-abrmd.service
sudo systemctl start tpm2-abrmd.service

5. Add user to tss group

Now you need to add your user to the tss group. This allows you to use the TPM daemon.

sudo usermod -aG tss $(whoami)

Afterwards refresh you environment.

newgrp tss

6. Verify the Installation

Test the installation by generating random data:

tpm2_getrandom --hex 8

If the output displays random hex values, TPM is functioning correctly.

With these steps, TPM TSS2 should be successfully installed and ready to use on your Ubuntu system.
