Sometimes CompatHelper 3 is not available

However, a significant percentage of the time, the job fails because only Compat Helper versions 0.1.0-2.1.1 are available. An example is here: . This failure seems to be random - sometimes it works fine. Is anyone else having this problem? Does anyone have an explanation? Will it resolve itself?
