I am running Debian 12 on my machine and today, after updating my system (but maybe not because of it) and restarting my machine, I got the following screen message:
There is an issue with Trusted Platform Module (TPM) data.
Press [Y] - Reset whole TPM
Press[N] - Boot with current TPM data
Note: BitLocker may require the recovery key to boot to Windows.
When selecting [N], I get to my password screen and I log in normally. However, when I restart my machine again, I get the same prompt. I am not entirely sure what TPM is used for - it seems that it is used for encryption, but I am not sure if I am/Debian is using it for anything. I am not entirely sure if TPM is used or not. I entered the BIOS menu and it looked like TPM was enabled. However, when I do
sudo journalctl -k --grep=tpm Jan 02 15:12:10 bactria kernel: ima: No TPM chip found, activating TPM-bypass!Is it safe to select "Reset whole TPM" in the startup dialogue? Can I check in any way if TPM is currently being used for anything? Are there any risks in resetting or turning it off?
Thank you,
Vangi
