Hello! I am attempting to simulate my robot in Gazebo9 with ROS.

I was able to get everything working on a VM, but when setting up a dedicated Linux Box using the same setup I am running into this error. To ensure the same 'setup' I have created a bash shell script for the install of ros, gazebo, needed packages.

Primary Issue: Exit Code 139.. No log file was created.

_OS: Ubuntu 18.04.4 LTS Bionic Beaver
_Memory: 3.8 GiB
_Processor: Intel Core 2 Duo E7300

Output from roslaunch:
(excluded roscore opening)

I was unable to determine the root cause of this error statement.

I was able to resolve my issue through checking and taking a few steps. If you are attempting to troubleshoot, I would suggest these steps.

Ensure Gazebo works in Standalone.
..Have you checked if you need to turn off hardware acceleration?

Is your environment setup properly? Sourced?
..Manually source your 'build' in each terminal.

Ensure Gazebo ROS & Gazebo ROS Control Packages are Installed

sudo apt-get install -y ros-melodic-gazebo-ros
sudo apt-get install -y ros-melodic-gazebo-ros-pkgs ros-melodic-gazebo-ros-control

Ensure the appropriate PID controller package is installed

sudo apt-get install -y ros-melodic-position-controllers
sudo apt-get install -y ros-melodic-effort-controllers
sudo apt-get install -y ros-melodic-joint-state-controller

Ensure your robot description and controllers are in the same namespace.
..I utilized a Xacro and have a <xacro robot: NAME> and a controller initializer that separately 'name' the robot. These needed to be the same (obvs) to function.
