Thanks, Rob Re: Error: Could not find or load main class com.intel.bts.BtsApp Just hit this issue, was able to make it work using the commands below. Seems like a javafx packaging issue with bts.jar. # Ubuntu 20.04 # Quartus-pro-21.1.0.169 # agilexfb_agfb014r24a2e3vr0_fpga_lt_reva_v20.4b72_v1.0/examples/board_test_system # export PATH=$QUARTUS_ROOTDIR/bin:$PATH sudo apt-get install openjfx java --module-path /usr/share/openjfx/lib --add-modules javafx.base,javafx.controls,javafx.fxml,javafx.graphics,javafx.media,javafx.swing,javafx.web -jar bts.jar
