Интернет-проблема доступа к сети Virtualbox kubernetes

Я плохо знаком с kubernetes, я устанавливаю два узла с помощью virtualbox узел для ведущего устройства и другого для рабочего. Я должен был перезапустить главный узел для расширения размера размера диска виртуальной машины, но после перезапуска я заметил, что сетевой интерфейс не заметил прежде docker0 и я больше не могу соединяться с Интернетом

от /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

autp enp0s3
iface enp0s3 inet static
address 10.0.2.15

и когда я работаю, я сталкиваюсь с этой ошибкой

root@kmaster:/home/master# sudo ip route add default via 10.0.2.1
Error: Nexthop has invalid gateway.

Примечание: Я работаю root@kmaster:/home/master# ip route flush dev enp0s3 перед выполнением sudo ip route add default via 10.0.2.1

и при попытке работать kubeadm init --apiserver-advertise-address=10.0.2.15 --pod-network-cidr=10.0.2.0/24

Я сталкиваюсь с этой ошибкой
