I see an answer (https://answers.ros.org/question/3212... ) saying to change in ~/.ignition/fuel/config.yaml, api.ignitionfuel.org to https://api.ignitionrobotics.org. But I think that I don't have ~/.ignition/fuel/config.yaml, because I'm looking and I don't found. Is it in some place or I need install? How?
