解决VMware虚拟机中Ubuntu 22.04无法联网, 安装VMwareTools失败，未发现软件包open-vm-dkms，open-vm-tools问题解决

尝试了网上很多教程，都是在Windows上修改网络属性，然而都没能解决，后来找到了解决方法。发现虚拟机里Ubuntu22.04系统桌面右上角并没有有线网络图标，尝试删除网络缓存文件后，重启网络后问题就解决了。解决方法
删除NetworkManager缓存文件

sudo service NetworkManager stop 

sudo rm /var/lib/NetworkManager/NetworkManager.state 

sudo service NetworkManager start

打开Ubuntu火狐浏览器，发现可以正常上网啦。

1. 看到官方支持的新命令，抛弃以往复杂的安装方式,只需要一行代码就能搞定

sudo apt-get install open-vm-tools open-vm-tools-desktop  open-vm-dkms

1. 在命令行输入回车之后
   E: 未发现软件包open-vm-dkms
   E: 无法定位软件包 open-vm-dkms
   然后查百度，输入

sudo apt-get update

然而并没有什么X用！！！
报错显示

W: Some index files failed to download. They have been ignored, or old ones used instead.

1. 百度了很多方法最后我决定换阿里云的源！！
   首先将/var/lib/apt/lists 的文件备份一下
   mkdir /var/lib/apt/list
   cp -r /var/lib/apt/lists/* /var/lib/apt/list
   然后删除/var/lib/apt/lists/文件夹下所有的文件
   sudo rm -rf /var/lib/apt/lists/*
   然后 打开/etc/apt/sources.list (emacs/vi/vim都可以用)

将里面的内容都删掉，替换成阿里云的源
因为换了几个源都发现还是会出现
index files failed to download的错误
所以我用了网上的几个源组合在一起

先复制好内容
vi linux命令行用d键删除行，用滚轮中键或shift+Insert来粘贴内容

1. 重新配置DNS；
   sudo emacs/vi /etc/resolv.conf

   
   # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
   #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
   nameserver 114.114.114.114
   naemserver 8.8.8.8
   #阿里的DNS
   nameserver 223.5.5.5  
   nameserver 223.6.6.6
   

2. 之后再运行sudo apt-get update 就成功啦！

3. sudo apt-get update

4. sudo apt-get upgrade

5. 运行

   sudo apt-get install open-vm-tools open-vm-tools-desktop open-vm-dkms

   成功安装VMwareTools
6. 输入sudo reboot重新启动即可使用VMwareTools
