I try to run a sample application in my Ubuntu 18 vm.

I have installed Docker client and server version of 18.06.1-ce. I already have VirtualBox running.

I use below link and install kubectl 1.14 too: https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-linux

I have Minikube v1.0.1 also installed. But Minikube start command stuck in Waiting for pods: apiserver and timeout

harshana@-Virtual-Machine:~$ sudo minikube start
  minikube v1.0.1 on linux (amd64)
  Downloading Kubernetes v1.14.1 images in the background ...

⚠️  Ignoring --vm-driver=virtualbox, as the existing "minikube" VM was created using the none driver.
⚠️  To switch drivers, you may create a new VM using `minikube start -p <name> --vm-driver=virtualbox`
⚠️  Alternatively, you may delete the existing VM using `minikube delete -p minikube`
