I have created a managed package in my Dev Org and that package has a listing on the Partner Org. Now the requirements have changed so I have removed the app from my listings. Now I want to delete the managed package present in my Dev Org but when I go to...
Create > Package > GIS (Package Name) > Delete
... It shows the following error:
"This Package cannot be deleted because it has the following uploaded versions:
Version Number: 1.0
Version Name: Winter 2016
