testcase #9 is always failed in minikube

[nam-jaehyun]

With minikube, all test cases except for test case 9 are passed.
However, test case 9 is always failed; thus, we need to check the reason and fix this issue.

@nam-jaehyun. Deploting kubearmor on minikube gives me this error which I think is related to ebpf support on minikube.

My minikube version is: v1.20.0

$ uname -a
Linux minikube 4.19.182 #1 SMP Wed May 5 21:20:39 UTC 2021 x86_64 GNU/Linux

I found this issue which might be related to this kubernetes/minikube#8556. I think I will need to have minikube with newer kernel versions in it(v5.x i guess). Can you please tell me the minikube version which you used?

@oneiro-naut did you install kernel-headers too?
In my case, I used this script to start Minikube.

@nam-jaehyun I didn't use the script earlier now I am using it. Thanks.
