完成镜像源配置后，执行以下命令更新软件包列表并升级系统：
sudo apt update
sudo apt upgrade
这样，Ubuntu 20.04的软件源将被配置为使用所选的国内镜像源，从而提高软件获取速度和稳定性。
ubuntu12.04怎么改变更新源
1、首先备份 Ubuntu12.04源列表
sudo cp/etc/apt/sources.list/etc/apt/sources.list.backup（备份下当前的源列表）
2、修改更新源
sudo gedit/etc/apt/sources.list（打开 Ubuntu 12.04源列表文件）
3、把里面的列表替换成下面的列表

ubuntu 如何更新软件源
在Ubuntu系统中更新软件源是一项重要的维护操作，可以帮助你获得最新的软件包。首先，打开终端窗口，进行备份操作，确保在更改源列表前保留原始设置。输入命令：sudo cp/etc/apt/sources.list/etc/apt/sources.list_backup，这一步骤将当前的源列表文件复制为备份。
接着，使用文本编辑器如gedit打开源列表文件，执行命令：sudo gedit/etc/apt/sources.list。在打开的文件中，将原有的内容全部删除，然后根据你的地区和网络环境，插入适合的源地址。例如，可以选择中国境内的镜像源，以提高下载速度和稳定性。
完成源列表的更新后，执行sudo apt-get update命令，更新源列表中的信息。在执行此命令时，可能会遇到连接失败的情况，这时需要检查并删除不可用的源，然后再次执行sudo apt-get update。
如果一切顺利，源列表更新完成后，就可以使用sudo apt-get upgrade命令来升级系统中所有可用的软件包了。通过这种方式，你可以确保系统的安全性，并及时获得最新的功能和改进。
