（二）ubuntu22.04 更新

本菜鸟起初是想安装qq微信，然后看到要安装wine
结果apt-get update时会出现Inrelease问题各种连接超时，无法更新，

第一步：换源

前提：下载文本编辑器Vim

~$ sudo apt-get install Vim

步骤：

1.备份原始源文件source.list
桌面右键打开终端，输入并执行命令：

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

2.修改源文件sources.list

sudo vim /etc/apt/sources.list

打开源文件，按i进入编辑，注释或删除（按d）原有的源，复制粘贴国内源，按ESC退出后，输入“:wq” 保存，按Enter自动退出。

国内源有阿里源，清华源，中科大源，个人用的中科大的，就是说hin快啊。

第二步：更新

# 更新镜像源
sudo apt-get update
# 更新软件
sudo apt-get upgrade  
#这个步骤以防后面安装依赖包，导致有些工具安装不上
sudo apt-get install build-essential
