Hi there,
I try my best to install IncusOS on a R730
Can anyone give me a hint how to solve the problem.
Thank you
Roger
@gibmat TPM issue?
Yeah, looks like the TPM isn’t becoming available during startup as expected (Timed out waiting for device dev-tpmrm0.device). I’d suggest trying a reset of the TPM from the BIOS and ensuring the SHA256 PCRs are enabled.
IncusOS depends on a working TPM (either physical or swtpm) when encrypting the root partition.
Hi,
thank you for your response. Unfortunately the tpm is not working. I bought one, which is detected in bios as you can see, but then there is another error in incus. Thus I disabled the tpm in bios.
We’ve run into some TPMs being sold out there with a very old firmware which makes them completely broken under Linux (and even Windows in some cases), so that may be what you ran into here.
You could always fully disable the TPM and download an image that works without the TPM (see advanced options at the bottom of the download page).
Just to point out, that error ERROR: open /sys/class/tpm/tpm0/pcr-sha256/4: no such file or directory is caused by your TPM not having enabled the SHA256 PCRs. As @stgraber mentioned, you might have a TPM chip with an old, buggy firmware.
So for some reason your physical TPM is still showing up to the running OS. It sounds like your physical TPM is a discrete module, could you try physically removing it, then seeing if the system boots as expected?
