Thanks for reporting it, there were problems with the wget commands. See #2330 .

Nice, thanks for the fast response!

I got around the wget issues, but now when trying to run the sydney_regatta, I get the following error:

[Err] [SystemLoader.cc:119] Failed to load system plugin: (Reason: Could not find shared library)

• Requested plugin name: [maritime::PublisherPlugin]
• Requested library name: [libPublisherPlugin.so]

I tried exporting the gazebo plugin paths to the binaries, but it still did not work.

export GAZEBO_PLUGIN_PATH=/home/per/gz-sim/tutorials/files/surface_vehicles/gazebo_maritime_ws/install/lib:${GAZEBO_PLUGIN_PATH}

I can't reproduce it. It works for me.

1. Did you compile the gazebo_maritime_ws?
2. Can you see libPublisherPlugin.so under ~/gazebo_maritime_ws/install/lib/?

Make sure that you're setting these environment variables as the tutorial describes:

export GZ_SIM_RESOURCE_PATH=$GZ_SIM_RESOURCE_PATH:~/gazebo_maritime_ws/install/share/gazebo_maritime/models
export GZ_SIM_SYSTEM_PLUGIN_PATH=$GZ_SIM_SYSTEM_PLUGIN_PATH:~/gazebo_maritime_ws/install/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/gazebo_maritime_ws/install/lib
