AWS - Can't detaching network interfaces - You are not allowed to manage 'ela-attach' attachments : <p>I did the AWS mysfits tutorial and I thought the cleanup would be as simple as deleting the Cloud Formation stack. However, items failed to delete so I am trying to clean them up manually to assist the Cloud Formation stack deletion.</p>

<p>I keep getting an error when trying to Detach the network interfaces (I am logged into the root account):</p>

<p>Error detaching network interfaces:</p>

<p>I am unable to delete my VPC without these being deleted.</p>

<p>The stack as a whole is failing to delete because of the following:
The following resource(s) failed to delete: [InternetGateway, PublicSubnetTwo, VPC, GatewayAttachement, PublicSubnetOne].</p>
