DKMS do not work on systems with Secure Boot enabled

Following an UOS approved spec, Ubuntu is checking module signing by default, on kernels 4.4.0-18.34, 4.4.0-21.37, 4.2.0-42.49, 3.19.0-65.73 and 3.13.0-92.139 onwards.

Because of those changes, DKMS modules will not work on systems with Secure Boot is enabled.

In order to make DKMS work, Secure Boot needs to be disabled. There are several methods to disable Secure Boot in your system:

Method 1 - Disable Secure Boot from BIOS

  1. Enter BIOS setup
  2. Disable secure boot
  3. Save configuration
  4. Reboot the system

Method 2 - Disable Secure Boot in shim-signed

  1. Open a terminal (Ctrl + Alt + T), and execute sudo update-secureboot-policy and then select Yes.
