I recently wanted to update my BIOS to F.21.I have ubuntu 20.04 LTS single boot.Using 7z I had extracted the exe file to a pendrive with fat32 format and booted my pc by pressing f9 using "boot from efi" and choosed the HpBiosUpdate.efi from there .But, my Bios isn't updated and shows bios update failed.Here is the log file after booting.
