Install fails on snap-core-2466.mount, unknown filesystem squashfs

Installation on my SolidRun Cubox-i armhf with snap fails with

Mount snap "core" (2466) ([start snap-core-2466.mount] failed with exit status 1: Job for snap-core-2466.mount failed.
cubox mount[2874]: mount: unknown filesystem type 'squashfs'

I have installed squashfs-tools. Others seem to have similar issues
