Title:
snapd fails always in Optimised Ubuntu Desktop images available in
Microsoft Hyper-V
I have verified (bionic 2.525.28 and disco 2.578.6) that the changes to
snap_preseed do not break existing functionality and that an error is
thrown when the helper _snap_preseed is called with an invalid snap
name, resulting in snap-info failing to retrieve the base.

FYI: Comment #8 (with comment #5) fixed the problem for me :-)

I should have been more explicit. When I wrote comment #28, the tests
*had not finished running yet* so it was false at that point.

again, please investigate.

I believe that comment #27 is correct, because after that the
autopkgtests for ubuntu-image succeeded (triggered by a qemu update)
using the previous revision of livecd-rootfs on disco. But I'm not able
to tell how the changes made to livecd-rootfs affect the
operation/testing of ubuntu-image.

Comment #27 is not correct.
I tested a bionic desktop ISO built with this livecd-rootfs and built
successfully and got core, so snaps work.
Not sure if that is sufficient validation for this bug, so I won't (yet)
change the tags.

Hello Peter, or anyone else affected,
Accepted livecd-rootfs into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/livecd-
rootfs/2.525.28 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See

Just as a heads up: the seed.yaml for the azure image also need
gnome-3-28-1804 in the seed. The `snap debug validate-image` will
validate all this once its landed so hopefully this will at least be
easy to detect fix (build-time instead of runtime).

To manage
My mistake that I didn't do proper error checking while determining the
base of a snap. This here
https://code.launchpad.net/~tobijk/livecd-rootfs/+git/livecd-

I ran the following test on the current version of livecd-rootfs for
Bionic:
https://pastebin.ubuntu.com/p/wQknctr6ys/
with a positive result:

So I think in principle it should work, but maybe there are silent
download failures. We definitely need
I have no understanding of the test process used to check a system
livecd build, but I imagine installing a snap that confirmed itself to
the test-system would be useful on each platform.

We also need to do more validation in "snap debug validate-seed":

creates the images? That's the project this bug needs to be assigned to.

yeah. That seed.yaml is missing core18, and those snaps need it AFAIK.

Title:
snapd fails always in Optimised Ubuntu Desktop images
I can confirm this bug is still present in the optimised 18.04.2 image,
and also verify that the commands from post #5 above worked for me to
fix it. I actually had to purge snapd twice, as the first time it failed
due to being unable to delete a folder with `rm` since it was a folder,
not a file.
This is a pretty bad first experience for 19.04 gallery image as its
supposed to be 'out of the box'. Must be lots of people trying this
first time in hyper-v gallery and giving up. Took few hours to find
this bug post. I can verify that the #5 commands corrected problem.
purge was needed.
I've had the same problem and purging/re-installing via apt package
manager is the only way I could figure out to fix it.

After a long and fruitless digging around systemd unit and seed.loaded I
have removed (purged) and installed snapd package and it fixed this
issue for me.
Something along the lines of:

$ sudo apt install snapd
$ sudo snap install core
