[Bug 2070070] Re: Support for Ubuntu Core tegra-igx images in jammy

[Andreas Hasenack]

Hello Loïc, or anyone else affected,

Accepted livecd-rootfs into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/livecd-
rootfs/2.765.44 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-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. 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.

** Changed in: livecd-rootfs (Ubuntu Jammy)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-jammy

Title:
  Support for Ubuntu Core tegra-igx images in jammy

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Jammy:
  Fix Committed

Bug description:
  This bug is to track changes needed to be able to build jammy Ubuntu
  Core images for arm64+tegra-igx to support hardware based on NVIDIA
  Tegra SoCs. NB some initial support had already been backported; see
  LP #2015644.

  [ Impact ]

   * This allows building missing image flavors for the NVIDIA Tegra families of hardware, notably Ubuntu Core images for the tegra-igx subarch.
   * This should also allow building of classic ISO installer images for tegra-igx, albeit that's a lesser priority.

  
  [ Test Plan ]

   * Changes to livecd-rootfs were tested locally and can be tested from the -proposed package by building a Core image for tegra-igx as follows:
  sudo apt install livecd-rootfs
  mkdir build
  cd build

  rm -rf auto local config
  rm -f livecd.*.model-assertion
  mkdir -p auto
  for s in config build clean; do ln -s /usr/share/livecd-rootfs/live-build/auto/$s auto/; done
  lb clean --purge
  export PROJECT=ubuntu-core ARCH=arm64 SUBARCH=tegra-igx SUITE=jammy IMAGEFORMAT=ubuntu-image CHANNEL=edge
  lb config
  sudo -E lb build

  
  [ Where problems could occur ]

   * Changes are relatively light, but in the case of a regression for
  instance due to broken logic, this could break existing image builds,
  in which case an older livecd-rootfs could be reuploaded.

  
  [ Other Info ]

   * These images are still being developed and its possible further
  changes are needed as we iterate through the maturity of the image.
