Posted 2022-02-16 FL1623863129

1.备份原始源文件source.list
打开终端，执行命令：sudo  cp   /etc/apt/sources.list   /etc/apt/sources.list.bak

2.修改源文件sources.list
（1）终端执行命令：sudo  chmod  777  /etc/apt/sources.list   更改文件权限使其可编辑；

（2）执行命令：  sudo  gedit   /etc/apt/sources.list    打开文件进行编辑；

（3）删除原来的文件内容，复制下面的任意一个到其中并保存（常用的是阿里源和清华源，推荐阿里源）；

阿里源：

3.更新源
桌面终端执行命令：sudo apt update更新软件列表，换源完成。

复损坏的软件包，尝试卸载出错的包，重新安装正确版本的 sudo apt-get -f install

更新软件 sudo apt-get upgrade

其他换源方法
还有一种更简单的方法，打开"软件更新器"，依次点击"设置"，"Ubuntu软件"，在"下载自"后面的窗口选择 "其它站点"在其中找到清华大学镜像站选择即可。
修改完软件源后，更新软件列表和软件

sudo apt update
sudo apt upgrade
