kernel snap for generic_amd64 devices

[Luke Williams]

Hi Marco,

I ran into the same exact thing. For some reason, the defconfig does not enable squashfs xz. You need to add that to your kconfigs section:
CONFIG_SQUASHFS_XZ=y

Then rebuild your snap using snapcraft and you’ll be good to go.


Thanks,
