.sh scripts are formatted in wrong mode for Linux version. They're formatted in Mac OS mode instead of Unix making them fail while being executed. Workaround is to copy and paste contents of script into a new .sh file. For instance making a new start.sh file, rename start.sh to start2.sh , and then create a new start.sh file with a text editor. Then using a text editor, copy entire contents of start2.sh into start.sh, then save and chmod 777 start.sh . After that it will work. Admins, please fix in next version so we don't have to apply this workaround every install.
