An item with the same key has already been added. The Extension cannot be unpublished because it is in use by the following tenants

Hi,

I am trying to Upgrade BC15 to BC 20. https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/upgrade/upgrade-unmodified-application-to-v20

When executing Get-NAVAppInfo I am getting more than 30 Extensions. In Business Central Extension Management I can see only 3 Installed. I tried to uninstall and unpublish all those extensions with no luck. (Before, I had more that I manage to delete them). 

When I am trying to uninstall (Uninstall-NAVApp) each of the 3 installed extensions I am getting error: An item with the same key has already been added.

When i am trying to unpublish (Unpublish-NAVApp) an extension I am getting error: The Extension cannot be unpublished because it is in use by the following tenants

Please help me identify the issue as I am not able to proceed with the upgrade

I have the same question (0)

    Do you have multiple tenants in your installation - if so you need to add the tenant parameter when you uninstall the app and uninstall it from all tenants before you unpublish it.

    Thanks for your answer!

    I do not have duplicate values in dbo.$ndo$navappschemasnapshot.

    Also, there are no $AppData tables because I didn't upgrade BC15, I thing this solution is for those who already upgrade their BC. I stuck in the early stage of  removing the extensions.

    Thank you
