I was browsing around since I just added TPM to my older motherboard and I wanted to check the full version. While browsing I stumbled across https://askubuntu.com/a/1415651/231142 where it is deleted. While they marked it as from SuSE Linux, the answer is exactly the same for Ubuntu.
Running that answer for my Ubuntu 22.04 LTS, I get this output.
$ cat /sys/class/tpm/tpm0/device/firmware_node/description
TPM 1.2 Device
Which seems very valid to me.
My question then would be do we leave this answer deleted even though it is a valid answer but mentions SuSE Linux?
