Failing with dependency violation

[uday-projectn]

I have tried to delete VPC, and it is able to delete through UI also.

But when ran with this sh file. Got below error.

./delete_vpc.sh us-west-2 vpc-0f904ff05c1a26ffc

An error occurred (DependencyViolation) when calling the DeleteSecurityGroup operation: resource sg-0063528210d054afa has a dependent object

Could you figure out the dependency ? Which object has adopted this SG?

@lianghong I had the same problem and I solved it here, when we are deleting a security group that has an inbound or outbound rule referring to another security group we have this problem, the solution found was to remove all the inbound and outbound rules and then remove the security group

This may be caused by Ingress and Egress policy in SG, try the new version
