#421 CloneZilla breaks Secure Boot while creating image.

[vas_smirn81]

I used Clonezilla-live- 3.1.3-16-amd64. On my laptop installed two OS: windows 11 and Ubuntu.
1. I created image from partition. As a result my laptop failed to boot. I didn't do restore from image, I just created image from partition. I received this error message when I tried to boot: "verifying shim SBAT data failed: Security policy violation. Something has gone wrong: SBAT self-check failed: Security policy violation." After this error message my laptop switched off.
After that I disable Secure Boot in UEFI/BIOS. It helps. I boot successful.
To fix Secure boot issue, I boot to Ubuntu and execute these commands:
sudo apt update
sudo apt install --reinstall grub-efi-amd64-signed shim-signed
sudo grub-install
sudo update-grub
It helps. I enable Secure Boot. And my laptop boots successful.
2. I created image from whole ssd disk. As a result my laptop failed to boot again with the same error message. Disable secure boot in UEFI/BIOS helps again. To fix Secure boot issue, I again boot to Ubuntu and execute the same commands as I typed above. But it doesn't help: if I enable Secure Boot, my laptop doesn't boot with same error message.

Could you help me to fix my Secure Boot issue?

So you meant the issue is about the restored OS (Ubuntu), not the Clonezilla live itself?
If so, maybe you can use Ubuntu installation CD/USB stick and enter rescue mode to fix that?
