Bionic builds can't build core18 images

[Łukasz Zemczak]

[Impact]

The livecd-rootfs branch is very outdated, so it was missing the per-series conditional for building core18 images. I did not expect this to be missing. Without it we still can't build core18 on bionic.

[Test Case]

Run a livefs bionic ubuntu-core build and make sure the right base: core18 model assertion is used.

[Regression Potential]

None. This code path is not used at all currently and will only be used once we get the ability to build core18 images (which is after this lands).

Hello Łukasz, or anyone else affected,

Accepted livecd-rootfs into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/2.525.35 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 and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. 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.

Ok, this finally seems to be working. I ran a bionic livefs ubuntu-core build with -proposed enabled and now I can confirm that the build pulled in the core18 assertion and built a core18 image in the end:

(as seen in the logs, livecd-rootfs 2.525.35 was used)

This bug was fixed in the package livecd-rootfs - 2.525.35

---------------
livecd-rootfs (2.525.35) bionic; urgency=medium

  * Did not expect the bionic branch being so outdated. Backport support
    for fetching core18 model assertions on bionic hosts. This enables build
    support for ubuntu-core 18 images. (LP: #1852332)

livecd-rootfs (2.525.34) bionic; urgency=medium

  * Add support for HyperV Gallery Images (LP: #1837088)
