Consider pinning runner image instead of using ubuntu-latest in JIT CI #125560
Description
It looks like GitHub updated the default/latest Ubuntu runner to use Ubuntu 24.04 from 22.04, which is leading to failed CI runs. We should consider pinning the version here.
(GitHub's general guidance is to use ubuntu-latest, so if folks feel strongly against this, this could also be a temporary measure until the issue resolves.)

We should consider this for all our runners, as long as we remember to bump them every once in a while. I've had issues in the past with
latestbreaking things after an update.savannahostrowski commentedon Oct 16, 2024
That said, I'm actually not sure if the image is missing dependencies...it seems like maybe something else has gone awry given that the error is actually a 503 on the workflow run.

The 503s look like temporary network errors. You can click the "Re-run jobs" button and "Re-run failed jobs". If the errors persist on ubuntu-latest aka ubuntu-24.04, we can pin (in the short-to-medium term) to ubuntu-22.04 if that fixes it.
In general, pinning is a good idea to avoid surprises like in #125236, then we can do a controlled upgrade.

Yeah, that makes sense. Thanks for sharing those other issues!
Updating to pin to 22.04 did fix things last night. Judging by the noise on social media around this...it seems like a bunch of things broke (some of which were more ephemeral).

It would be nice to have them pinned and make updating them part of something in the release cycle, maybe on tagging of alpha0.
hugovk commentedon Oct 17, 2024
Unfortunately, I don't think we can schedule them: we get Ubuntu releases every second year, and it will depend a lot on availability of the image on GitHub Actions, plus readiness of other dependencies.
For example, alpha0 was 8th May, and
ubuntu-24.04was available on (checking...) 14th May. That's not so bad, actually :) But it was a beta, the GA was last month, and when we checked upgrades in August, some things weren't ready, like Azure Pipelines (#122544).And I wouldn't want it to be part of the release cycle (but it could be prompted by it) - there can be some non-trivial upgrades needed, and we wouldn't want to delay any part of the release because of it.
