Hi Jon, Can you clarify a little bit more about what you mean about conflicting dependencies? The only known issues have been related to upstream debian packages we depend upon which have changed. Also if you are on shadow-fixed this is possible as we sometimes roll back releases in that repo. And as Mike mentioned dist-upgrade is required if there are new dependencies added. I don't know of anything in the ROS release system itself has nothing inherently causing conflicts except that it's very active with a large user base making many releases. If you have some examples we can take a closer look at what caused them.
