I use Ubuntu22.04 and Fortress！  
Does anyone know how to solve this problem?  
I didn’t see this file “libignition-gazebo-world-stats6-system.so” in the folder “usr/lib/x86\_64-linux-gnu/ign-gazebo-6/plugins”  
And I even repeated the following steps several times.  
sudo apt remove ignition-fortress && sudo apt autoremove  
sudo apt-get update  
sudo apt-get install lsb-release gnupg  
sudo curl [https://packages.osrfoundation.org/gazebo.gpg](https://packages.osrfoundation.org/gazebo.gpg) --output /usr/share/keyrings/pkgs-osrf-archive-keyring.gpg  
echo “deb [arch=(dpkg --print-architecture) signed-by=/usr/share/keyrings/pkgs-osrf-archive-keyring.gpg] http://packages.osrfoundation.org/gazebo/ubuntu-stable (lsb\_release -cs) main” | sudo tee /etc/apt/sources.list.d/gazebo-stable.list \> /dev/null  
sudo apt-get update  
sudo apt-get install ignition-fortress  
But there is no such plug-in.  
Thank you very much for everyone’s reply
