Yesterday I upgraded from 19.04 to 19.10. Today it doesnt boot correctly and shows this error.
error: can't find command `hwmatch`
error: Unknown TPM error.
Press any key to continue...
Pressing any key didnt bring me further. I had to press the power button for a few seconds. After turning it on again I see this:
Ubuntu
Advanced options for Ubuntu
System Setup
When I select Ubuntu I get those errors:
Initramfs unpacking failed: Decoding failed
tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer.
tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer.
After those errors I can login and work with Ubuntu.
Update: Commenting the lines of code described here grub issues message at boot - "error - can't find command hwmatch" did not solve my problem.
Update: I made a bootable usb with 19.10 to reinstall Ubuntu. Sadly after the install I got the same errors again.
Update: Flashing the BIOS of my Asus UX560QK to the newest available version 307 didnt work neither. I got the same result.
As you might have realized I am a beginner in Ubuntu. Any help would be appriciated!
Update: I managed to bypass this problem by disabling Secure Boot in UEFI.
