Title:
  Missing fuse deb package when trying to preseed snaps

Status in livecd-rootfs package in Ubuntu:
  Expired

Bug description:
  I tried to build an arm64 image on AWS (with ubuntu-bartender):

  ./scripts/ubuntu-bartender/ubuntu-bartender --no-cleanup --build-
  provider aws --aws-arm-build --aws-instance-type m6g.xlarge --hook-
  extras-dir ~/devel/canonical/cloudware/cpc_packaging.extra/ --livecd-
  rootfs-dir /home/tom/devel/livecd-rootfs/ --  --series focal --project
  ubuntu-cpc --minimized --image-target ec2

  The build fails with:
  + snap_validate_seed /tmp/tmp.9FX9CNOMhi
  + local CHROOT_ROOT=/tmp/tmp.9FX9CNOMhi
  + '[' -e /tmp/tmp.9FX9CNOMhi/var/lib/snapd/seed/seed.yaml ']'
  + snap debug validate-seed /tmp/tmp.9FX9CNOMhi/var/lib/snapd/seed/seed.yaml
  ++ realpath /tmp/tmp.9FX9CNOMhi
  + /usr/lib/snapd/snap-preseed --reset /tmp/tmp.9FX9CNOMhi
  ++ realpath /tmp/tmp.9FX9CNOMhi
  + /usr/lib/snapd/snap-preseed /tmp/tmp.9FX9CNOMhi
  error: cannot mount /var/lib/snapd/seed/snaps/snapd_11843.snap at /tmp/snapd-preseed in preseed mode: exit status 32

  
  So snap-preseed can't mount the snap. Trying to do that manually (from within the chroot) also fails:
  # mount -t fuse.snapfuse -o ro,x-gdu.hide,x-gvfs-hide /var/lib/snapd/seed/snaps/snapd_11843.snap /mnt
  mount: /mnt: wrong fs type, bad option, bad superblock on /var/lib/snapd/seed/snaps/snapd_11843.snap, missing codepage or helper program, or other error.

  The reason is, that the fuse .deb package is not installed. Installing
  that package into the chroot solves the problem.
