[Bug 1848892] Re: "error: Unknown TPM error." after upgrading to grub 2.04
Also reported for ubuntu 19.10 with kernel 5.3.7 I could see no logs upon boot, only a purple screen that appeared to hang forever. Disabling TPM in BIOS had no effect on the issue, as tpm is a kernel module it is automatically loaded upon boot. The trick is to enter the grub 2.04 console by pressing c, and then entering `rmmod tpm` feel free to run it again to make sure the module has been removed. That should do it Then boot in with ctrl+x or F10 This is just a workaround and not a permanent fix, the entire community expects this bug to be fixed ASAP as there is not solution for it besides removing the module manually on each boot, or recompilling your kernel with the removed module. None of which is a long-term solution I hope this helps somebody -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848892 Title: "error: Unknown TPM error." after upgrading to grub 2.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1848892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Further work may be needed later to correct or mitigate these errors if TPM measurements are needed to work on the affected systems, as such measurements would otherwise be incomplete. + + --- + After upgrading to eoan today (via `do-release-upgrade -d`), my laptop failed to boot into the OS. I got the grub 2.04 screen (showing only Ubuntu), but selecting that gave me about 20 lines of "error: Unknown TPM error.", followed by "error: you need to load the kernel first" and no way to proceed/recover. Advanced options didn't work either. Dropping into the grub console and writing a simple command like `set root=(hd1,gpt5)` failed again with a TPM error. It goes without saying that booting had worked before with disco/grub 2.02. As a workaround, I eventually managed to boot using an eoan live CD, chroot'ed into my system, added the `disco main` repo, and forcefully downgraded to disco's 2.02.

I've already submitted a possible fix upstream for this issue (well, at least something that will stop this breaking, and give us more information to debug and fix it more permanently): https://lists.gnu.org/archive/html/grub-devel/2019-10/msg00103.html There isn't concensus there just yet, but I will prepare the SRU for this today, and I think this is a good candidate for releasing quicker than the usual 7 day waiting period in the -proposed repository. This means I'll still need help from people to give us debug information once the patched version of GRUB is available so we can better understand what was going wrong exactly. In the meantime, the best solution is to: - Get to the GRUB menu - Highlight the boot entry you wanted to run and hit E (for edit) - At the top of the entry, add "rmmod tpm" - Hit Ctrl-X or F10 to run the edited entry. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848892 Title: "error: Unknown TPM error." after upgrading to grub 2.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1848892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

My affected system is an ASUS Zenbook UX305FA with Secure Boot turned off. Thanks for all the hints, especially comment #10. My workaround was easy: 1. In grub menu, choose an entry and edit it (key press: e). 2. Add rmmod tpm in a line before the first insmod. 3. Boot with the modified entry (key press: F10). 4.

[Bug 1848892] Re: "error: Unknown TPM error." after upgrading to grub 2.04
On a 19.04 system, I don't see the /boot/grub/x86_64-efi/tmp.mod file-- so added during the upgrade. Speculation: So, the problem might be related to signed versus unsigned kernels. The earlier kernel was probably signed. The new kernels from the upgrade are probably not signed. Can't test right now, but will follow up with another laptop. I will upgrade to 19.10 in the same way. Using command: dpkg --list | grep linux-image to list kernels lists past kernels not currently installed.

[Bug 1848892] Re: "error: Unknown TPM error." after upgrading to grub 2.04
I also blah, blah, blah, upgraded Kubuntu to 19.10 and updated to
5.3.0-19-generic.
System:
ASUS GL553VE Laptop
GPT Disk with EFI partition
No TPM module installed that I can determine
BIOS:
Latest == 308
No TPM settings
Turned off Secure Boot and CSM
GRUB Boot Error:
error: Unknown TPM error. (multiple)
error: you need to load the kernel first
FIX:
Boot a broken system:
'c' to command line
grub> rmmod tpm
'esc'
Select any boot option to boot normally
Fix GRUB once booted:
sudo grub-install --no-uefi-secure-boot /dev/sd
reboot
I'm documenting my experience in the following details so that maybe
somebody can figure it out and finally fix the effing thing.
Apparently, I had an older kernel {from 19.04?) that would boot even though I
had a later kernel installed. I didn't notice the grub failures as I had:
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
and the system was apparently failing. When I changed:
#GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
I thought I was borked! I rebooted and left it while I did some research. It
apparently had time to fall back to the earlier working kernel which surprised
me. In the attempt to clean the system, I did a "sudo apt autoremove" which
really did bork my system as the fallback kernel was now gone.
I looked all over the intertubes and found little help--even this post,
I fiddled with turning on and off the BIOS Fast Boot, CSM, and Secure
Boot to no effect.
I guessed on trying to remove the tpm module during the grub boot as
above. The grub documentation is VERY POOR at describing how specific
modules get loaded. The tpm.mod file has no "insmod" command anywhere
on the system. However, the /boot/grub/x86_64-efi/ directory has a
moddep.lst file that shows the dependencies between modules and files:
tpm <- verifiers <- normal <- many others. Automagically, tpm.mod gets
loaded. I suppose I could have set a "rmmod tpm.mod" in a
/etc/default/grub.d/40-custom.cfg file, but that didn't seem really
elegant.
So, grub is apparently detecting and demanding Secure Boot even though it's off
and the installed vmlinuz and initrd files can't get validated. I don't know
why the earlier kernel didn't fail. I tried a manual boot with:
grub> ls
to get the disks
grub> set root=(hd0,1)
grub> linux /boot/vmlinuz-5.3.0-19-generic root=/dev/sda1
Failed with the "error: Unknown TPM error."
grub> initrd /boot/initrd.img-5.3.0-19-generic
Failed with the "error: you need to load the kernel first"
Of course!!! because "linux" failed to set linux
grub> boot
FAIL!
Then, I did:
grub> rmmod tpm
Complains with the "error: Unknown TPM error."
But works because a repeat doesn't produce the error message
Repeat "linux"
No error
Repeat "initrd"
No error
grub> boot
SUCCESS!
Then, I eventually worked my way around to the "grub-install" man pages
and saw the "--no-uefi-secure-boot" and "--uefi-secure-boot" switches.
What if...YUP! Turning off UEFI Secure Boot for the grub install did
it. Why the hell can't grub get it right from the BIOS settings? Why
is tpm.mod failing in this odd way? Why did the older kernel work when
tpm.mod is loaded and the newer ones did not?
Working for now, but I know any possible automatic grub update with a
"grub-install" will bork it in the future.
