Ubuntu更新源
<p>安装Ubuntu后，使用国外源太慢了，修改为国内源会快很多。今天就简单给大家说一下Ubuntu更新源 命令的操作过程。</p><p>以 Ubuntu 18.04 为示例，将默认的源修改为国内阿里源，具体的操作教程如下：</p>
<h3 id="1备份-etcaptsourceslist">1、备份 /etc/apt/sources.list</h3>
<p><code>cp /etc/apt/sources.list /etc/apt/sources.list.bak</code></p>
<h3 id="2默认源修改为阿里源">2、默认源修改为阿里源</h3>
<p><code>vim /etc/apt/sources.list</code></p>
<p>添加以下内容：</p>

<p>deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse<br>
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse<br>
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse<br>
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse<br>
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse<br>

<p>3、最后执行如下命令 更新源列表以及升级软件</p>
<p>sudo apt-get update<br>
sudo apt-get upgrade</p>
<p>顺便再给大家分享一下其它的国内Ubuntu更新源：</p>

<hr>
<p>最近换回ubuntu14.04来使用笔记本,发现阿里云的更新源总是apt-get update && apt-get upgrade以后就会报错，懒得解决了，就重装了三次。<br>
3d桌面在官方源下面可以顺利安装完成，但是vscode在14.04下安装了居然卡顿，百度了半天也没找到合适的解决办法，哎。。。，看有人说需要安装ubuntu make<br>
我也装了 还是卡，决定先放弃了，随后再折腾，因为在kali里习惯了zsh，现在还得装这个玩意<br>
