I have an ASUS G752vs laptop running Linux Mint LMDE 3 and Windows 10. I'm thinking of replacing LMDE with Debian 10 Testing. Therefore, today I downloaded and created three Debian Live Testing USB sticks using the following ISOs:
debian-live-testing-amd64-xfce.iso
debian-live-testing-amd64-cinnamon.iso
debian-live-testing-amd64-gnome.iso
Unfortunately, I receive the following error messages with all three:
After pressing "Debian GNU/Linus Live (kernel 5.2.0-2-amd64)" I see:
error: Unknown TPM error.
error: Unknown TPM error.
error: You need to load the kernel first
Press any key to continue...
I'm then returned to the main screen
If I press Debian Live with Localisation Support
I see a full screen of "error: Unknown TPM error.", followed by "Press any key to continue..."
I'm then sent to a screen to choose my language with GNU GRUB version 2.04-3 at the top.
After choosing English, I receive the first set of error messages noted above.
To trouble shoot, I have done the following:
1. Tested the live testing USBs in an older desktop computer without TPM ... They work fine.
2. Created a USB with debian-live-10.1.0-amd64-cinnamon.iso ... It works fine on my laptop.
3. I thought maybe it was a kernel issue. So I created a live USB with Manjaro xfce 18.1.0 (which has kernel 5.2.11). It ran without any issue on my laptop.
So in summary, the only combination that didn't work was the Debian testing with my Laptop.
Any ideas why the live testing ISOs is throwing the TPM error and is there anything that I can to do to resolve the issue?
P.S. I have disabled secured boot in the bios and that didn't resolve the issue. The laptop also does not have the option to disable TPM in the bios as it is running Intel's TPM 2.0 version 11.0.2 1003.
Thanks,
Richard

Re: TPM error with Live Testing ISO
Looks like a GRUB issue. TPM support was added to GRUB in testing recently. See https://www.gnu.org/software/grub/manua ... sured-Boot for some information.
Can the laptop boot in BIOS/legacy mode ?

Re: TPM error with Live Testing ISO
A GRUB issue makes sense. Although I'm surprised that I didn't run into the same issue with Manjaro as they also use GRUB 2.04. I've read more on this, but unfortunately I can not find anything that helps resolve this issue.
The laptop cannot boot in BIOS/legacy mode.

Re: TPM error with Live Testing ISO
Thank you p.H, I've reported the issue to the Debian developers.

Re: TPM error with Live Testing ISO
I haven't received any response and many of the bugs on the GRUB page ( https://bugs.debian.org/cgi-bin/pkgrepo ... ckage=grub ) are over 10 years old.
I would like to be able to use Debian Testing, however until this matter gets resolved, I'm in a holding pattern.
Can anyone confirm that I filed the bug in the right place or provide an alternative where I should file it?

If you want to install Debian testing, you can install a Debian stable base system and upgrade to testing.
Or you can boot the Debian testing installer with a GRUB instance which does not show the error, such as the one from Debian stable or LMDE.
Or you can do the installation on another machine which does not show the error.
However, if you manage to install Debian testing, it is likely that its GRUB will suffer from the same problem.
