Just installed the new LTS.

Previous setup from 17 failed to setup efi?

I believe that error refers to a read-only file system, perhaps that's why DKMS failed.

Ubuntu 18.04 may not need fwts-efi-runtime-dkms as efi_test driver should be included in kernel.

Please run "modinfo efi_test" for more info of this driver

@jefchan,

I think you should be able to run efi tests, ex. sudo fwts uefirtvariable without the dkms since efi_test.

We will also investigate how to solve this dkms on signed kernel..

[Alex Hung (alexhung)]

We may be able to use BUILD_EXCLUSIVE_KERNEL and BUILD_EXCLUSIVE_ARCH for the dkms, ex

BUILD_EXCLUSIVE_KERNEL="4.1*" (since efi_test is included in 4.10
BUILD_EXCLUSIVE_ARCH="amd64"

See details @ http://manpages.ubuntu.com/manpages/bionic/man8/dkms.8.html

[Alex Hung (alexhung)]

Currently all Ubuntu kernels that are not EOL include efi_test except 4.4. As a result, we can build & install the dkms only for kernel 4.4 such as below:

+BUILD_EXCLUSIVE_KERNEL="^4.4"

A test built (versioned 18.05.01) is available on https://launchpad.net/~firmware-testing-team/+archive/ubuntu/scratch. I tested on 4.13 (secure boot disabled) and 4.15 (secure boot enabled) - both show the module is skipped.

[Alex Hung (alexhung)]

Fixed committed to repo

[Alex Hung (alexhung)]

The fix is removed from 18.06.2 because it fails ADT test. Please see more information @ LP/l1777855. This needs another proper fix.

[Alex Hung (alexhung)]

Now DKMS are ready when UEFI Secure Boot is enabled, and it will prompt MOK key enrollment (see screenshot) when DKSM packages are installed.

The process requires a reboot. When system is rebooted, MOK will also ask for passports and confirmation of key enrollment, and DKMS package will work correctly when Ubuntu boots.
