Replace LXD deb by snap in Ubuntu 18.10

autopkgtest *only* uses the `lxc` CLI and documents the `lxd` setup CLI from $PATH. The package has a "Suggests: lxd-client". You mention that the "lxd" deb will remain around, does that apply to "lxd-client" as well?

The only binary package left post-transition will be "lxd". The "lxc-client" and "lxd-tools" binary packages will be removed from the archive.

For autopkgtest, it sounds like we'll just need to change the Suggests to point to lxd rather than lxd-client which should be fine even in the current world (as lxd-client alone isn't that useful).

Ah, it used to be useful for running the containers on a remote servers. I. e. what we used to do for armhf testing, they were running on remote arm64 OpenStack instances.

I adjusted the Suggests: https://salsa.debian.org/ci-team/autopkgtest/commit/4d4a7d9b16f

Thanks!

Thanks Martin!

So looks like we're in good shape with removal of "lxd-client" and "lxd-tools" as only Suggests remains and that's autopkgtest which will be switched over to "lxd" soon enough.

I'm now checking the rdepends of lxd to ensure that they deal with the snap as expected.

I've confirmed that adapt from the cosmic archive works just as well with the snap as it does the deb.

And confirmed that snapcraft (cleanbuild) similarly works just fine.

From the perspective of nova-lxd, there isn't a problem with the snap version (as pylxd already works with a snap version of lxd). However, the lxd charm will need to be altered to ensure that it installs / otherwise manages the fact that lxd is supplied in snap form.

We do have some utilities to support installation of payloads from snaps, but obviously, this is work that would have to be scheduled. I'll chat in the OpenStack team about this and report back.

Ok, going to close the nova-compute-lxd task then as it sounds like from a packaging point of view we're good, it's external integration (charms) that may run into problems.

Note that since we will still have a "lxd" package in the archive which auto-installs the snap for you, things may just work though obviously we'd prefer for the charm to actually install the snap rather than depend on the deb shim.

Marking bug as block-proposed so we keep the transitional package in proposed for now.

And package has now been uploaded to cosmic-proposed.

All autopkgtest failures have been dealt with, we're now all green and only held by this bug's tag.

I intend to clear the tag, allowing for lxd to transition to the release pocket on Monday.

There will likely be a bit of bumpiness afterwards as seeds and meta packages get updated (2-3 hours), then we'll see how the various images behave.

As planned, releasing this to the release pocket by removing the blocker tag.

This bug was fixed in the package lxd - 1:0.3

---------------
lxd (1:0.3) cosmic; urgency=medium

  * Install the snap on package installation too, not just upgrades
  * Make snapd a Pre-Depends for the case where snapd isn't installed
