Based on some recent comments on that upstream tracking issue, it seems like GitHub's plan is "from now until March 2023, slowly increase the number of runners for which `ubuntu-latest`...

> Is the IN_UBUNTU_LATEST_CONTAINER variable only set in Azure? Yep! That's a LightGBM-specific thing, and only used on Azure. Maybe we should rethink that. Specifically, maybe we should try to...

@jmoralez I don't think that's correct. The most recent runs I pushed just installing `libomp-dev` ([link](https://github.com/microsoft/LightGBM/actions/runs/3700586066/jobs/6269144099)) failed like this: ```text E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13:...

Ha yeah sorry! The most recent commit I pushed got us a bit closer. Now just the `Linux_latest gpu` jobs are failing. I see this error further up in the...

I'm working on this in #5597.
