Hi,

what's the correct way for installing Gazebo in a system with ROS2 Crystal?

The following instructions are not working at the moment

$ docker run -it osrf/ros:crystal-desktop bash

$ apt-get update
$ curl -sSL http://get.gazebosim.org | sh
The following packages have unmet dependencies:
libgazebo9-dev : Depends: libavdevice-dev but it is not going to be installed
              Depends: libignition-fuel-tools1-dev but it is not going to be installed
              Depends: libignition-common-dev but it is not going to be installed
              Depends: libgazebo9 (= 9.8.0-1~bionic) but it is not going to be installed
              Depends: gazebo9-plugin-base (= 9.8.0-1~bionic) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Note that I get a very similar error also if I run

$ apt-get install -y ros-crystal-gazebo-ros-pkgs

As a solution, I have explicitly installed some dependencies before calling the gazebo install command

$ apt-get install -y \
   libwayland-egl1 \
   libsdl2-2.0-0 \
   libavdevice57
$ apt-get install -y \
   libgazebo9-dev \
   gazebo9
$ apt-get install -y  ros-crystal-gazebo-ros-pkgs

This works, but as a result I can't run rviz2 anymore.

This works and it's better than my command. Actually I think that my problem was also due to the use of a not up-to-date base image

BTW @marguedas you might find rocker useful if you're running gui's inside docker https://github.com/osrf/rocker it's available from the ROS repos as python3-rocker or via PIP.

If you don't need all of the isolation of Docker (but are using it more as part of a deployment system), you could also take a look at Singularity. Wrappers like rocker aren't really needed with it.
