just for clarification, in Linux with any program when installing in terminal, if dependencies are missing they will cause an installation error, you need to read the terminal after each command to verify if the installation was successful or if there was a complication that needs to be addressed, it will give you any clues as to what is wrong very clearly. so in your example, there are missing dependencies as shown in the terminal boxed in red outline. the solution is to immediately run after that installation command the following command shows in red text. that should resolve and then the previous installation will continue automatically and complete. now if you ignored any of the dependency errors in previous installation lines for linuxcnc, hiyapyco, qtpyvcp, you would need to go back and rerun those in the correct order from the docs and running the dependency fix directly after each. the order is important because each item is a dependency of the previously installed component.
linuxcnc > hiyapyco > qtpyvcp > probe-basic
