TPM configuration fails on a Thinkpad T510 due to missing kernel modules

Question

[Running 14.04 LTS.]

I'm trying to setup the TPM chip on my T510. I've been following the instructions at https://askubuntu.com/a/414755/507853 but I'm having the following issue:

I've tried rebooting but it makes no difference. The TPM is already enabled/active from my previous Windows 10 install (I also double-checked in BIOS just to be sure.)

Is someone able to help?

Try running depmod -a and then repeat your modprobe commands.

According to the man modprobe:

modprobe expects an up-to-date modules.dep file, as generated by depmod. This file lists what other modules each module needs (if any), and modprobe uses this to add or remove these dependencies automatically.

As soon as this file was updated, use modprobe command without paths and .ko extension:

modprobe module_name
