[SOLVED] Failing to delete Network Interface AWS

Issue

I am trying to delete my vpc and I first need to delete my network interface. However, those cannot be deleted because they are still in use. I terminated all my ec2 instances and still, the interfaces are in use and cannot be detached even cannot be forced detached. They are of the type efs mount target.

Solution

Those interfaces are currently in-use and you cannot delete them directly.

1. You can select each interface and check which resources are using right now. As I can see at the description part, EFS service and it's not related to EC2 services.
2. Each EFS filesystem has a network interface (ENI) per its subnet for communication. If you want to remove those interfaces, you need to delete the EFS filesystem first.
