Just try to install AM in Lubuntu 20.04 LTS through by VM. It works fine. The step is below. One thing would like to highlight. I got complie error "g++: fatal error: Killed signal terminated program cc1plus" while I set the memory is 1G. The issue was gone when set to 2GB.

sudo apt-get -y install make g++ git libsfml-dev libopenal-dev libavformat-dev libfontconfig1-dev ibfreetype6-dev libswscale-dev libavresample-dev libarchive-dev libjpeg-dev libglu1-mesa-dev
git clone http://github.com/mickelson/attract attract
cd attract
make -j $(cat /proc/cpuinfo | grep -c processor)
sudo make install
After installed, you may create application shortcut icon on desktop. Open text editior to create new file as below content and then save as .desktop extension
