[Bug 2027686] Re: Recent update has broken Focal buildd images

[Steve Langasek]

I have rolled back livecd-rootfs in focal-updates to 2.664.47, the
previous version.

However, the purpose of this livecd-rootfs SRU was to fix a build
failure that was expected to impact all buildd image builds when using
the new launchpad livefs builder code.

Were the daily buildd images not failing to build in focal without this
change?

If they were, then rolling back livecd-rootfs doesn't help much, since
the latest daily build will still be the one that fails.

  Recent update has broken Focal buildd images

Status in livecd-rootfs package in Ubuntu:
  Confirmed

Bug description:
  It appears a recent update to livecd-rootfs
  (https://launchpad.net/ubuntu/+source/livecd-rootfs/2.664.48) has made
  buildd images non-bootable using QEMU.  So far, I've found this
  affects daily Focal buildd images, but as of this writing, I'm still
  testing out other series.

  Running QEMU by hand such as we would in Multipass along with the QEMU
  console shows that it gets stuck at the grub prompt.
