ubuntu20.04清华源

Ubuntu 20.04可以使用清华大学开源软件镜像站作为源。在终端中，使用以下命令打开编辑器：
sudo vi /etc/apt/sources.list
在编辑器中，将原来的源地址替换为清华大学的源地址。清华大学镜像源的网址是 https://mirrors.tuna.tsinghua.edu.＊＊＊保存并退出编辑器。完成修改后，运行以下命令以更新源信息：
sudo apt update
这样就将Ubuntu 20.04的源更换为清华大学的源了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
