问题：
操作系统：Ubuntu 22.04.3 LTS
VMware 版本：VMware® Workstation 17 Pro, 17.0.0 build-20800274
今天在虚拟机用Ubuntu的时候，发现无法连接网络，如下：
wd@wd-virtual-machine:~$ ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536inet 127.0.0.1 netmask 255.0.0.0inet6 ::1 prefixlen 128 scopeid 0x10<host>loop txqueuelen 1000 (本地环回)RX packets 3771 bytes 269507 (269.5 KB)RX errors 0 dropped 0 overruns 0 frame 0TX packets 3771 bytes 269507 (269.5 KB)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0解决办法：
百度后找到的解决办法：
wd@wd-virtual-machine:~$ sudo service NetworkManager stop
wd@wd-virtual-machine:~$ sudo rm /var/lib/NetworkManager/NetworkManager.state
wd@wd-virtual-machine:~$ sudo service NetworkManager start
wd@wd-virtual-machine:~$ ifconfig

sudo service NetworkManager stop
sudo rm /var/lib/NetworkManager/NetworkManager.state
sudo service NetworkManager start
现在可以上网了：
wd@wd-virtual-machine:~$ ping baidu.com

解决VM虚拟机中ubuntu系统上不了网的问题，请直接看方法四，前面三种方法都没什么用，至少我是这样的。还有就是他的文章中停止和启动的命令中的network-manager我需要换成NetworkManager才可以。
