vmware ubuntu 异常关机无法连接到网络

step1: 查看所有的网卡

ifconfig -a

可以看到ens33 这个不work了

stdpain@ubuntu:~$ ifconfig -a
ens33: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 00:0c:29:45:7a:69  txqueuelen 1000  (Ethernet)

重置网卡:

sudo service network-manager stop 
sudo rm /var/lib/NetworkManager/NetworkManager.state 
sudo service network-manager start

执行 ifconfig -a

stdpain@ubuntu:~$ ifconfig -a
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
