How to update a nuget package which is already uploaded in nuget.org

I had uploaded a nuget package into nuget.org. Now i want to update just the nuspec file.Is there a way to update the nuspec file of already uploaded package.

I see an option to Manage,but it shows only deprecation and Listing.

Is there a way to update the licenseInfo link. There is an additional character in the link which i want to remove,is there a way to do it?
