Hi Thomas,
I've followed the above steps, but still I am getting error while deleting the package from the repository workspace. I am surprised to see that old project packages are showing in my new repository workspace root folder. Whereas I have deleted the whole project and also checked in my local machine. My old projects doesnt exist. But I can see the old project packages are still in new project repository workspace root folder. The following error I am getting while Select the package and choose Activate from the context menu,
"An internal error occurred during: "Activating packages".
At least one resourceId is required"
