Hi all,

I'm using ros2 humble.
Launching the command ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py I have the following error

Have you got any suggestions how to solve it?

[fatemeh-mohseni-AI]

killall gzserver
killall gzclient

delete ros2_ws and recreate it .
then :
colcon build

retry. It might be resolved

[Tanishq30052002]

doesnt work

[manavthakkar]

It worked for me

[Tanishq30052002]

for me source gazebo worked

[mrRasoul]

I still have the problem!
Is there a chance that you might have fixed it?!

source /usr/share/gazebo/setup.sh

Try adding the same to your
.bashrc

[sathvik0320]

yes using source /usr/share/gazebo/setup.sh
solved my error
[ERROR] [gzserver-1]: process has died [pid 27337, exit code 255, cmd 'gzserver /home/sathvik/4wheel/install/control/share/control/model/empty.world -slibgazebo_ros_init.so -slibgazebo_ros_factory.so -slibgazebo_ros_force_system.so'].

[offgrid88]

It is sourcing source /usr/share/gazebo/setup.sh most of the time or a hanging gz client or server
anyone can add an alias
alias killgazebo='killall -9 gzserver || true; killall -9 gzclient || true'
to bashrc and make sure gazebo is killed

[PAyush15]

killall gzserver killall gzclient

delete ros2_ws and recreate it . then : colcon build

retry. It might be resolved

Thanks! That solved the issue for me.
