Hey @chaltonh,
As @Andres.Aulasneo points out above, Ironwood is no longer (officially) supported at all. If running Maple is an option for you, I guarantee you’ll have much better luck installing it. If Maple is not an option, then Lilac would be second best: even though it is also no longer supported (AFAIK the community only officially supports the latest release), there are plenty of people still running it in production.
I know this doesn’t help you if you’re stuck with a fork, or even if you don’t have the resources to go through the upgrade process. But even if painful, it is usually less expensive to upgrade than trying to maintain an old release, precisely because you can then rely a little more on the community to help you. (Ask @sambapete: he’ll tell you all about it.
