Cannot delete VPC due undeletable ENIs

Question

I'm having trouble deleting a VPC I no longer need.  
  
The VPC was originally created through cloudformation for an EKS cluster. When I was done with that cluster I deleted the stack(s) and the cluster, but there are still some resources left over:  
- VPC itself  
- 2 subnets, route-tables, security groups,  
- 2 ENIs  
  
It seems that the ENIs are the issue, all the other resources point to those and say I need to remove these first. But even with my root account credentials an attempt to detach these ENIs gives: "You do not have permission to access the specified resource."

Answer

Hello ronnyroe,  
  
I have checked your AWS Account and I could see from CloudTrail that you were trying to detach 2 ENIs recently. However the operations failed with the error "You do not have permission to access the specified resource.". As you haven't provided the ENI id I am assuming that these are the 2 resources in question.  
  
The 2 ENIs belong to your AWS Elastic Load Balancers (ELB) \[1]. If you wish to delete the ENIs you need to first delete the related ELBs \[2].  
  
I hope that you find this information helpful. Please let us know if you need any further help.
