Did you try addressing the configuration issue ?

VirtualBox is configured with multiple host-only adapters with the same IP "192.168.99.1". Please remove one

Thank you. You are right. I used the VirtualBox tool to remove all the dangling host virtual adapters then it worked. I noticed that these virboxnet# interfaces are left over after "minikube delete" . The delete command removed the vms but didn't clean up the interfaces. I repeated a couple of times of start and delete, the virtual interfaces that created by minikube always left there without cleanup.

@gitpop I am curious, are you running this on a cloud VM ? like compute engine ?

[medyagh]

@gitpop would this help ?

vboxmanage list -l hostonlyifs | grep 192.168.99.1 -5 | grep -w "Name:" |  awk '{$1=""; print $0}'

and remove each returned vboxnet
vboxmanage hostonlyif remove INSERTNAME

I confirm this issue exists, on the virtualbox test box we have more than 21 left over adapters

 vboxmanage list -l hostonlyifs | grep -w "Name:" |  awk '{$1=""; print $0}'
 vboxnet21
 vboxnet19
 vboxnet12
 vboxnet20
 vboxnet18
 vboxnet7
 vboxnet1
 vboxnet10
 vboxnet14
 vboxnet6
 vboxnet15
 vboxnet9

 vboxnet5
 vboxnet3
 vboxnet13

 vboxnet4
 vboxnet11

or if you want it in one command, one important thing I noticed, you have to deleted it with the same user that runs minikube.

vboxmanage list -l hostonlyifs | grep 192.168.99.1 -5 | grep -w "Name:" |  awk '{$1=""; print $0}'  | xargs -l vboxmanage hostonlyif remove

Remove one of the boxes with the same IP address, that will solve this problem.

Closing as there is a workaround.
