Rapid Photo Downloader 0.9.0a4 is released

I’m struggling to get this installed on a Raspberry Pi. I had version 0.9 working with Ubuntu on a netbook and now I’m trying to get it installed with Ubuntu Mate on a Raspberry Pi 3. 0.4 runs but I was having issues getting it to scan iOS so that is why I want 0.9 but it will just not install. If I run the installation script with 0.4 installed, it does not overwrite and running the app opens 0.4. If I uninstall the 0.4 package and run the installation script I get a “No such file or directory” error. Any idea what I am missing?
