From possible solutions from Stackoverflow: http://stackoverflow.com/questions/21415156/unable-to-recreate-missing-debug-keystore and http://stackoverflow.com/questions/20788875/android-studio-unable-to-recreate-missing-debug-keystore

Android apps are digitally signed as proof they are valid apps from a verified source. When you release an app and put it up on Google Play or other app stores you need to create a release key and sign the app with it. This is all gone over in the next course, Publish an Android App, so don't worry too much about the details of doing that yet.

While you're writing and testing your app it still needs to be signed. Android Studio automatically generates a "debug key" for you to do that. In your case, it's having trouble. Either a path isn't set right or your .android directory is read-only.
