Public bug reported: When installing acpi-call-dkms in Ubuntu 20.04 with secure boot enable, a password (MOK) is asked. However, this password is not asked upon reboot... Therefore the key is not enrolled and the acpi_call cannot be used : "modprobe: ERROR: could not insert 'acpi_call': Operation not permitted" Disabling secure boot (of course) solves the problem. I noticed that after installing acpi-call-dkms and before rebooting, "sudo mokutil --list-new" says that "MokNew is empty".
