Several services in Labs, tools, and prod rely on packages from the mirantis apt repo. That repo doesn't work, so those systems currently cannot be rebuilt.

One bandaid we could try would be to gather up packages from /var/cache/apt/archives/ on our hosts and put them into an aptly repo. This is obviously a very temporary solution, but arguable better than not being able to rebuild a box if it goes down.
Jessie-backports currently has Mitaka package versions. As noted by Mortiz on irc it is unlikely that those packages will be updated again now that stretch is released. There is a bit of scariness in not having an easy way to pin our installed packages to the mitaka versions like the Mirantis repos did, but its probably something we can survive.
In looking at a total move to Debian as solution there is at least one glaring issue in that the cadence of stable=>backports(testing) from next release does not seem to follow a N+1 release cycle. For instance Jessie=>Stretch=>Buster is poised to miss Ocata entirely. That's a pretty significant hurdle if it's sane for us at all.
Notes from investigating:
OpenStack Upgrade release policy states
We only test N to N+1 in the CI system (the grenade jobs) so while things might work in practice by skipping a release, it's not tested that way upstream at all so any chance of it working is accidental and shouldn't be relied upon or really expected to be supported that way upstream.
A the moment it sure looks like there is no way to avoid a troubling and expected faulty version jump from jessie=>stretch=>buster (ocata is missing)

I've been assuming that we need to move to source-based deployments since Debian seems determined to do this the wrong way. I've contacted the debian packager (Allison Randal) several times about this but haven't gotten any useful responses.
Skipping versions seems semi-possible if we have to, but given the current cadence I don't have a lot of faith in how they'll handle this going forward.
I can add a bit more details.
- Ocata (v11) was not packaged for Debian on purpose
- There are 2 options for using Ocata in Debian: build ourselves the packages OR use the ultimum.io repo
13:25 <arturo> DebianDeveloper: did you read my message regarding keystone v10 --> v11 --> v12?
13:26 <DebianDeveloper> arturo: Not sure, can you say again?
13:27 <arturo> sure
13:27 <arturo> DebianDeveloper: http://snapshot.debian.org/package/keystone/ <--- there seem to be no upgrade path for keystone in debian, right?
13:27 <DebianDeveloper> arturo: I skipped packaging Ocata, indeed, but we do have the source code available in the Git.
13:28 <DebianDeveloper> So you "just" need to rebuild it from the Git.
13:28 <arturo> I see
13:28 <arturo> was there any technical reason for the skip?
13:28 <DebianDeveloper> There's also a repository with backports for Ocata in Stretch done by the CZ people.
13:29 <arturo> oh, could you share the link?
13:29 <DebianDeveloper> arturo: There's a social one: I got out of employer, and was a bit demotivated, plus I expected others would pick-up, which never happened.
13:29 <arturo> DebianDeveloper: ok, understood
13:30 <DebianDeveloper> arturo: repo : deb http://debian.ultimum.io debian-stretch ocata ocata-backports
13:30 <DebianDeveloper> apt_key : http://debian.ultimum.io/apt.key
13:30 <arturo> thanks!
13:31 <DebianDeveloper> arturo: I thought about publishing that on a debian.net repo, but so far, I didn't.
13:31 <arturo> that would be great, indeed
13:32 <DebianDeveloper> arturo: If I was to publish Pike and Queens on official Debian backports, would you use it?
13:32 <DebianDeveloper> That's about 3/4 days of work, which is why I don't want to do it for nothing.
13:33 <arturo> DebianDeveloper: I fully understand the think about sharing efforts et al
13:34 <arturo> DebianDeveloper: about Pike/Queens, we are currently evaluating in the team how to do new deployments
13:34 <arturo> I bet for using Debian, that's for sure, but others in my team prefer source deployments
13:35 <arturo> (one of the points being the upgrade path thing)
13:39 <DebianDeveloper> arturo: If using sources, it means you're re-inventing all what's in the package maintainer's scripts. That's a huge amount of work.
13:40 <arturo> I see
13:42 <arturo> from the resources point of view, I guess there is little we could do from my team, given we are a non-profit foundation, fully donation-based income. Our resources are very limited. I wonder what happens with the big company players out there
I've checked the ultimum.io repo by hand and it's full of packages, apparently ready to use.
- openstack mitaka is in jessie-backports (already using it in eqiad1)
- openstack newton is in stretch (mitaka+1)
- openstack ocata is in stretch-backports (newton+1)
Closing task now.
