A fix has been implemented and we can confirm that we're not seeing any new occurrences of the errors.

In case your builds were affected and if you haven't modified the image(s) you were initially using, you can now rerun the builds.

The issue appears to only occur for jobs using `machine: true` or older images.

As a workaround, we suggest specifying a recent machine image. You can find a list of available machine images here:
