Hi Kyle,

I had been (with 0.14 snap) building the image and saving to file with -o

Then mounting the img partitions with (as root):
kpartx -a my.img

mount $loopmtn DIR
With 0.15, that mount fails with a Kill message.
Can you provide the exact failure you're seeing? What version of Ubuntu are
you on? It works for me on Zesty:
* xenial
* my model points at branded store that contains learnit snap
* I add three snaps to the image via --extra-snaps
ubuntu-image \
--channel stable \
-o $image_name \ (LOWERCASE -o)
--image-size 4G \
--extra-snaps pi2-kernel_26.snap \ this is local
--extra-snaps pi2_36.snap \ local
--extra-snaps learnit \ from branded store into which it is
whitelisted via store admin
$model
=== snap experience
$ sudo kpartx -a test-learnit.img
[sudo] password for knitzsche:

That does not happen with the ubuntu-image from deb on xenial (see below)

Partition size/offset need to be a multiple of sector size (512). The
size/offset will be rounded up to the nearest sector.
% sudo kpartx -a pc.img
