I have Ubuntu 16.06 running on a 2007 Mac Mini.
I downloaded the linux version;
I unarchived it keeping the driectory (folder) structure;
I see a “lightrun” file that’s executable, but when I right-click and say “Run”, nothing happens: no screen, no error message.
I also see an Apprun executable file, but that also does nothing when I try to run it.
Both of them are marked as “Execute: Allow executing file as program” under Permissions.
I’ve searched forums and the web - no joy yet - hope you can help.
