The final error in the log regarding the database upgrade piece is this:
Error| Database Updates failed for org c9619898-6674-4669-97a6-a970a4b10237 with exception: Microsoft.Crm.CrmException: Update Organization with Id=c9619898-6674-4669-97a6-a970a4b10237 failed with Exception:

Further up in the log file each one of those solution/packages that are referenced in the error above I see the follow exception:
Info| Failed to install msdynce_OfficeProductivityAnchorException: Microsoft.Crm.CrmException: Crm Internal Exception: Singleton Retrieve Query should not return more than 1 record.
at Microsoft.Crm.ServerLocatorService.TryGetCrmUserIdFromDatabase(Guid organizationId, String authenticationInfo, Guid& crmUserId)
They all reference that 'Singleton Retrieve Query should not return more than1 record'. I don't know a way to get more info about what query it is running to see where there appears to be some duplicate records that shouldn't be. Anyone have any suggestions on how to get this updated to the latest CU? Thanks in advance for any and all help!
