Bug Description

[Impact]

For 20.04.2 we need to offer both the GA and HWE kernels in our ubuntu-server images, which currently is not the case as we missed the step of enabling both ga and hwe kernel variants in livecd-rootfs. This is required for 20.04.2.

[Test Case]

Start a -proposed enabled livefs ubuntu-server-live focal build (can be a build via cdimage as well). Make sure that the livefs build results in two sets of kernel+initrd pairs.
If tested via cdimage, additionally it might be good to check the actual image if HWE is selectable.

[Where problems can occur]

The change is self-contained only to the ubuntu-server-live image paths, so the only places where issues can occur is in kernel selection for the images. No other possibilities.

Hello Łukasz, or anyone else affected,

Accepted livecd-rootfs into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/2.664.13 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Built an ubuntu-server-live image with PROPOSED=1 via cdimage. The resulting livefs build seems correct:

https://launchpad.net/~ubuntu-cdimage/+livefs/ubuntu/focal/ubuntu-server-live/+build/257451

Files resulting from this build:
    livecd.ubuntu-server.initrd-generic (80.0 MiB)
    livecd.ubuntu-server.initrd-generic-hwe (83.6 MiB)
    livecd.ubuntu-server.installer.squashfs (233.2 MiB)
    livecd.ubuntu-server.kernel-generic (11.1 MiB)
    livecd.ubuntu-server.kernel-generic-hwe (9.3 MiB)

    livecd.ubuntu-server.squashfs (356.7 MiB)
    livecd.ubuntu-server.squashfs.manifest (15.5 KiB)

As seen, the build now results in both GA and HWE kernels present. Looking at the build logs, I have confirmed that the correct livecd-rootfs version was used (2.664.13). Ready for release.
