Snapcraft pc-kernel failed

[mborzecki]

there’s an example of snapcraft.yaml with some modifications right here:

Custom core20 image: boot error: file '/kernel.efi' not found

In the snapcraft.yaml definition, you can change some of the make variables: I’ve changed the MIRROR below, for example: make-parameters: - KERNEL_SOURCE=focal:linux-uc20-efi - KERNEL=linux-pc-image - KERNEL_IMAGE_FORMAT='$(if $(filter x86_64,$(shell uname -a)),efi,vmlinuz)' - PROPOSED=true - MIRROR=gb.archive.ubuntu.com/ubuntu build-packages: - debootstrap - gnupg - kmod - lsb-release

Note how KERNEL_IMAGE_FORMAT is set there.
