My installer is broken. I can't install any new applications, install any updates, or uninstall any applications. Whenever I try to do any of this it downloads the package, starts going through the processes and then just quits installer and goes back to the home screen. It never has that little wheel spin in the center of the screen and then goes to lock screen like it normally would when you install/uninstall a program. I have tried turning it off and back on and nothing will fix it. Does anyone know how I can fix this issue without reinstalling the OS?
