SharePoint App Deployment error : 'Failed to install app for SharePoint'

Question

When I tried to add a SharePoint mvc app I am getting following error:

Error occurred in deployment step \'Install app for SharePoint\': 
Failed to install app f         


        

Answer 1

In my case I got this error when I inadvertently changed the TemplateType value in the instance's Elements.xml file .without making the same change in the Element's Definition (the other Elements.xml directly under the Elements root).

Therefore there was a mismatch in the two elements.xml of the list being deployed.
