ignition-gazebo is a rewrite of the good old Gazebo (Gazebo classic) which is designed to supersede it. Can be seen as a ROS 1 vs ROS 2 evolution since they share some important aspects like the break of compatibility with the antecesor. It is hard to say that the replacement is ready since it mostly varies with everyone's use case. There is a table that can help in this front: https://ignitionrobotics.org/docs/edifice/comparison
Thanks, looks like a lot of features are there while a bunch is still missing. Not sure if it makes sense to update already, but I don't use Gazebo currently so your call.
I have the feeling that there is a large community of people now using Gazebo that will take some time to migrate to ignition-gazebo for different reasons so my personal preference would be to be able to have both available in Debian during some time to give people time to plan the migration.
But are they bound to Gazebo or also to a specific ROS and Ubuntu version?
So my view here would be to upload ignition-gazebo once it is ready and then see if supporting the old version makes sense.I agree. Problem here is that if we upgrade some of the ignition libraries to new major versions, Gazebo classic has never been tested to compile or work with the new major versions so it is unknown if the new mix would work in the same or compatible way with previous mix of Gazebo + supported Ignition libs major versions.
Yeah, I mean gazebo plus libraries in the corresponding version. Having multiple versions of software in Debian for a transition period seems quiet normal.
Cheers Jochen
