That's fair - maybe I expressed it badly or just that it's hard to come up with succinct rules for questions. Consider two scenarios : a) I have installed some software X but messed up one of the install steps and now there is this weird error. Or b) when installing this software, it always errors if library Y is on an old version. For b) it is clearly a 'general' problem that many people will face. For a) it could be seen as a user error and therefore not generally useful. From the point of view of the people facing a) though, it absolutely is a problem!
