Why am I getting an error when I request a security review?

The following errors may occur when you request a security review for your listing.
This partnership is already linked to another AppExchange Provider Profile.
This error means that your partner account is associated with a different Salesforce organization. The organization associated with your partner account is known as your AppExchange Publishing Organization (APO), and it is the only organization from which you can publish to the AppExchange. To solve this error, link the organization(s) where you developed your app to your APO. If you do not know which organization is your APO, log a case in the partner portal for assistance.
To security review your application, you must be a salesforce.com partner and connect your partnership information to your provider profile. To connect this information, please login using your master AppExchange Publishing Organization and edit your provider profile.
Your AppExchange provider profile (that is, the provider profile associated with your APO), must be linked to your partner account before you can submit a listing for security review. This requirement streamlines the review process downstream by ensuring that partners have access to the partner portal and that they've agreed to the terms and conditions. To resolve this error, log into the AppExchange Publishing page using the credentials for your APO and add your partner account information to your provider profile.
