ifconfig查看IP地址遇到的一系列问题

想用python虚拟环境，网上下载了ubuntu20.4镜像装了一个vmware虚拟机

http://mirrors.aliyun.com/ubuntu-releases/20.04/  ubuntu20.4下载地址

 

打开后ifconfig没有ip地址

终端运行 sudo apt install net-tools 后提示软件包net-tools没有可安装候选

需要更新软件源

sudo apt-get update

更新很慢，到最后还出现了报错

想试试重新更新的时候出现了无法定位软件包错误

我百度之后更换国内软件源可以解决

打开源配置文件

sudo gedit /etc/apt/sources.list   (gedit和/中间加个空格)

将里面的内容更换为国内阿里的源地址

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

 

其他源可自行百度

保存退出

就能正常安装net-eools后查看ip地址了
