We're still using Jessie because we need to build breakpad client minidump-stackwalk and haven't updated that to work with more recent versions of ... I think it's gcc and/or libs. Anyhow, I haven't been able to build those with stretch.

According to this:

https://lists.debian.org/debian-devel-announce/2019/03/msg00006.html

the jessie things we're using have moved.

We're unable to build images now--this completely halts development and deploys and needs to get fixed.

This bug covers figuring that out.

We really should update to stretch. The recent versions of the Python Docker image we're using are all built on stretch, so we've been blocked from updating to new versions.

I'm going to try to update to stretch and see if I can work out compilation issues.

Making this a P1 to tackle now.

willkg merged PR #4863: "bug 1539272: switch to 3.6.8-slim-stretch" in a75f831.

I had tried to do this a while back, but hit problems with building the breakpad client. Those problems must have been solved by one of the breakpad client upgrades we did. So this turned out to be pretty easy to do.

Everything is good here. Marking as FIXED.
