一、预备工作

1. 下载VMware并安装

(许可证：ZF3R0-FHED2-M80TY-8QYGC-NPKYF)

2. 下载Ubuntu镜像

Ubuntu20.04

二、 新系统调整

1. 软件换源

  • 在换源之前，要先对原来的源进行备份，在Ubuntu中，软件源存在/etc/apt/sources.list中，用以下命令备份：

    1
    sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

  • 打卡文件 /etc/apt/sources.list：

    1
    sudo gedit /etc/apt/sources.list

  • 删除文件里的内容，并复制要换的源（如阿里源）：

三、番外篇

1. VMware的完全卸载

Vmware卸载后会有残余，这会导致我们再次安装后出现各种问题，非常麻烦，于是以下是Vmware完全卸载的方法。

  • 将Vmware相关的服务停止，如下：

    image-20210915225708434

  • 删除注册表

    image-20210915231814731

  • 在任务管理器结束Vmware相关的进程

  • 卸载Vmware程序

  • 结束！
