ubuntu更新国内软件源
<p>国内有很多Ubuntu的镜像源，包括阿里的、网易的，还有很多教育网的源，比如：清华源、中科大源。<br>我们这里以清华源为例讲解如何修改Ubuntu 18.04里面默认的源。</p><p>1、输入命令修改sources.list文件，当然需要超级权限，所以要加sudo；</p>
<p>sudo vim /etc/apt/sources.list</p>
<p>编辑/etc/apt/sources.list文件</p>
<p>2、在文件最前面添加以下条目(操作前请做好相应备份)：</p>
<p>deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse<br>deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse<br>deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse<br>deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse<br>deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse<br>deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse<br>deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse<br>deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse<br>deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse<br>deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse<br><br>3、修改完成后，保存文件，警告什么的都不理，然后运行下面的命令。</p>
<p>sudo apt-get update<br>sudo apt-get upgrade</p>
<p>4、到此完成国内源更新。</p>
