That probably means the file isn’t marked as an executable, so the program used to handle the file type is opened. I know you’ve now solved this by installing from OBS, but for future reference:
- each file has a number of permissions, like ‘readable’, ‘writeable’, ‘executable’
- only files that are marked ‘executable’ can be run directly.
In whatever file manager you use, you should make sure the file is marked executable. For example:
Once you do that, a double-click will run the application.
