What does the error message "repository not owned by current user" mean after upgrading?

edit

This error message usually indicates that the user who is currently logged in does not own the repository that they are trying to access or modify. This may occur after upgrading if the ownership of the repository has changed, or if the user has changed their username or login credentials. To resolve this issue, the user may need to contact the repository owner or administrator to request access or ownership permissions. Alternatively, the user may need to update their login credentials to ensure that they have the necessary permissions to access the repository.
