[Bug 2057888] Re: Private store may not contain lxd snap

[Aristo Chen]

> What do you mean?

Previously, when we were using u-i tool 2.x to build 22.04 classic
image, we had a hook(https://git.launchpad.net/~lyoncore-
team/lyoncore/+git/iot-image-builds/tree/hooks/post-populate-
rootfs.d/030-snap-prepare-image.sh?h=classic22.04-uimg2#n17), and the
code was copied from foundation team  by one of my colleagues in CE team
AFAIK

> You mean reset the preseeding anyway? Or skip the preseeding entirely?
I am also not sure to understand why your problem is linked to resetting
the preseeding.

I think the root cause is var/lib/snapd/state.json is not handled
properly. By deafult, there is lxd and core20 snap in that
file(var/lib/snapd/state.json), but the customer may not want to include
those snaps in their private store, so skip checking that
file((var/lib/snapd/state.json)) could solve this issue, or probably we
can remove that file(var/lib/snapd/state.json) directly? I am not sure
if remove the file(var/lib/snapd/state.json) will affect any other use
cases, so that's why I think having a flag somewhere(probably in the
yaml?) could be better

Title:
  Private store may not contain lxd snap

Status in Ubuntu Image:
  Incomplete

Bug description:
  Hi,

  I defined core22 and snapd in extra-snaps, but the ubuntu-image 3.x
  will also try to download lxd snap after downloaded core22 and snapd,
  and lxd is actually not included in the private store

  If I understand correctly, in internal/statemachine/classic_states.go,
  the function prepareClassicImage will try to check the file called
  var/lib/snapd/state.json, and tries to preseed the snaps defined in
  that file afterwards. However, lxd snap may not be included in private
  store, then it will fail to preseed the snap.

  Previously in ubuntu-image 2.x, we leveraged the
  commit(https://git.launchpad.net/livecd-rootfs/commit/live-
  build/functions?id=b43e3b84f4c9100379f4686f80699929c7657056) from
  foundation team, I don't know if this mechanism should be integrated
  into ubuntu-image 3.x as well? Or maybe we can have a flag to skip
  checking var/lib/snapd/state.json?
