There is no inherent problem with mixing stages and chaining, as far as I know. Both are simply facades on top of Puppet's underlying relationship machinery, so fundamentally they are parts of the same thing. I am pretty confident that the problem is with Class<| |>. There are at least two factors in play there: 1. Classes are not resources. PL has made a concerted effort since the introduction of v. 2.6 to blur, downplay, and obscure the distinction, but they have not removed it. 2. Resource collections are conflated with realization of virtual resources (or collection of exported resources, where there isn't even a distinct name for the concept). There is a longstanding ticket on this issue. Since classes are not resources, but collection syntax specifies, in part, realization of virtual resources of the specified type, I do not find it surprising that Puppet rejects Class<| |>. It looks like it should work (because PL has done a good job of making classes appear to be resources), but I'm not surprised that it doesn't. I would not consider that a bug per se, but that it should work as you expected seems a reasonable feature request. > I could put the installation of apt sources in their own run stage > that runs first.

Does it not work to put your Apt::Source resources into their own classes, and assign those classes to your initial stage? That seems the natural solution.
