[Bug 1879350] Re: need uc20 grade=dangerous channel=beta images built

[Launchpad Bug Tracker]

This bug was fixed in the package livecd-rootfs - 2.664.3

---------------
livecd-rootfs (2.664.3) focal; urgency=medium

  [ Łukasz 'sil2100' Zemczak ]
  * Enable overrides of UC20 grade dangerous channels - as this is possible.
    (LP: #1879350)

  [ Iain Lane ]
  * Hack seeding of linux kernel in ubuntustudio/focal
    ubuntustudio-default-settings in focal release has a Recommends to this
    kernel, which makes it impossible to update the kernel later on, since we
    would install the -updates and release kernel, which isn't allowed and
    causes FTBFS. Hack out the focal-release kernel and let the rest of the
    build process pull in the right one. (LP: #1884915)

Bug description:
  [Impact]

  We need the ability to build arbitrary-risk-level dangerous images for
  UC20.

  [Test Case]

  Fire up a livefs build of ubuntu-core on focal using the -proposed
  version of livecd-rootfs, with CHANNEL=dangerous-beta and observe if
  the build succeeds, with the dangerous model being used and the
  channel overriden to beta.

  [Regression Potential]

  UC20 builds can be potentially affected for unrelated channel
  combinations. That being said, the exact same change is being used for
  UC20 builds since long (via the snappy PPA) and no regressions have
  been observed.

  [Original Description]

  We need the following things:

  1. canonical signed model assertions for a uc20 image with grade==dangerous, channel==beta for the various supported platforms, i.e. right now generic pc-kernel amd64 and armhf pi-kernel and arm64 pi-kernel models
  2. livcd-rootfs + cdimage builds of images for the above model assertions
  3. somehow these builds get published onto http://cdimage.ubuntu.com/ubuntu-core/20/dangerous-beta/ (or some other new directory there that does not conflict with the current set of dangerous, edge and beta)
