Kernel Snap Build Fails



I am trying to build kernel snap and I am getting below build error

Verify that the part is using the correct parameters and try again.

My snapcraft.yaml is

name: pi2-kernel
version: 4.4.0-1109.117
summary: The canonical raspi2 armhf kernel
description: The Ubuntu linux-raspi2 kernel package as a snap
type: kernel
confinement: strict

source-type: git
source-branch: master
plugin: make
- KERNEL=linux-image-raspi2
- PKGS=raspberrypi-wireless-firmware bluez-firmware
- debootstrap
- lsb-release

Can you point what is the issue here.



I’d use plugin: kernel instead :wink:


Thanks Ogra. I would check on this.

btw, If i want to compile the plain vanilla kernel snap for raspiberry pi 3 , what I need.
I am able to compile this snap from launchpad but I am unable to complie from ubuntu 18.04 classic running on arm using snapcraft.

What is the requirement to compile the kernels if needed.

thanks and regards
