Builds have been working fine this week - last night they suddenly stopped working. Re-running previously successful builds are also failing at the same point :

CircleCI received exit code 100

This is the common failure for all of them - not necessarily at the same point but the same step and the same reason.

status.circleci.com looks fine - thoughts?

One of the failed workflows : https://app.circleci.com/pipelines/github/SeanCannon/aca-client/34/workflows/84c3522c-e091-4d70-b1ea-a15a913d222e/jobs/40

I have a similar issue. I was using:

  build:
    machine:
      image: circleci/classic:201711-01

and switched to:

  build:
    machine:
      image: ubuntu-1604:201903-01

With either image, I’m getting a lot of 404s on a build that was otherwise working:

sudo apt-get install -y git python3 curl python-pip

python3 is already the newest version (3.5.1-3).
python-pip is already the newest version (8.1.1-2ubuntu0.4).

This seems to have resolved itself today - builds working fine again. Anything we should know about from @CircleCI-Employees ? Or just a hiccup we can disregard? Next time would be helpful if these types of issues were reported in the status check page.
