How to remove gazebo-ros-pkgs
I would like to update Gazebo to version which fixes important for me bug. ROS Melodic's gazebo-ros-pkgs still contains Gazebo 9.0.0 which is a bit outdated. Therefore I need to remove package and install gazebo manually. However simple apt command will for some reason remove a lot more than just one package:
sudo apt-get remove ros-melodic-gazebo-ros-pkgs
Here is output:
The following packages were automatically installed and are no longer required:

Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
ros-melodic-desktop-full ros-melodic-gazebo-ros-pkgs ros-melodic-simulators
As you can see it is to remove three packages ros-melodic-desktop-full ros-melodic-gazebo-ros-pkgs ros-melodic-simulators. Why so and how can I update gazebo?
Thanks!
Because
ros-melodic-simulatorsdepends onros-melodic-gazebo-ros-pkgs, so if you delete the second,aptmust delete the first.Same for
desktop-full.@gvdhoorn it's actually as clear as it may be. I should have put the question differently here. Why would
ros-melodic-desktop-fulldepend onros-melodic-gazebo-ros-pkgs? Gazebo is a separate app which has actually nothing to do with ROS. And I still have no found a solution to the problemPlease refer to REP 150: ROS Melodic and Newer Metapackages and REP 3: Target Platforms. Gazebo is a stand-alone application, but ..
..
gazebo_ros_pkgsisn't (it depends on Gazebo). Second,desktop-fullis a:which happens to include the
simulatorsmeta-package. Andsimulatorsprovides pkgs that get used when using simulators with ROS, including the (almost) standard .... simulator Gazebo. Gazebo itself is not directly depended on, but
gazebo_ros_pkgsis, and that brings in Gazebo.So: remove Gazebo -> remove
gazebo_ros_pkgs-> removesimulators-> removedesktop-full.I didn't post this as answer, ..
.. I wanted to comment on one of the questions in your post.
Have you seen Installing gazebo_ros_pkgs (ROS 1) and Which combination of ROS/Gazebo versions to use?
This is weird, I didn't remember to have this issue when I uninstall gazebo's packages from the Kinetic version, even If I had installed, if my memory is good, the full version. In the worst case, just uninstall the full version and take the desktop one. By the way, I used synaptic to uninstall it.
