[Bug 1901803] [NEW] package grub-efi-amd64-signed 1.142.8+2.04-1ubuntu26.6 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess was killed by signal (종료됨)

[Anselmo Park]

Public bug reported:

When I command 'sudo apt upgrade', the progress bar stopped at 91%.
A kworker related to grub consumed 100% CPU. (It uses only one CPU. The others were idle.)

Dmesg message had error about watchdog and it occurred repeatedly.
