[Bug 1517582] Re: flash-kernel causes postinsts to fail when it happens to be installed on an unsupported system

[Newell Jensen]

Trying the export as was mentioned (I believe in the correct way):

root@(none):/# export FLASH_KERNEL_SKIP=1
root@(none):/# apt-get --reinstall install linux-image-4.2.0-1-arm64; echo $?

As I am still seeing the error, is there another way that I should be
exporting this to the environmnet?

  on an unsupported system

Status in flash-kernel package in Ubuntu:
  Invalid

  For xgene-2 soc on EFI system, flash-kernel is failing:

  Unsupported platform.
  run-parts: /etc/initramfs/post-update.d//flash-kernel exited with return code 1

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

  This error surfaced during the deployment of a Wily MAAS arm64 daily
  cloud image.  http://cloud-images.ubuntu.com/daily

  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center

  I mounted the root-image that MAAS and overlayroot use as the
  OverlayFS.  I located the changlog for flash-kernel and found the
  package information below:

  flash-kernel (3.0~rc.4ubuntu55) wily

  3) What you expected to happen

  I expected that postinsts would not fail.

  4) What happened instead

  postinsts failed.
