issue in deleting VPC and network interface

Question

I am trying to delete aws vpc (a non default one). I am getting error that \"We could not delete the following VPC (vpc-xxxxxxx (xx.xx.xx.x/16)) Network interface \'eni-xxxx

Answer 1

As @karimtabet said, the VPC I was unable to delete was still assigned to an active RDS instance. after removing this RDS instance, I was able to delete the VPC.
