我在下面简单说明一下：

cd /etc/apt/
sudo gedit sources.list

更换源如下

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse 
  deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse 
  deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse 
  deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse 
  ##测试版源 
  deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse 
  # 源码 
  deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse 
  deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse 
  deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse 
  deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse 
  ##测试版源 
  deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse 
  # Canonical 合作伙伴和附加 
  deb http://archive.canonical.com/ubuntu/ xenial partner 
  deb http://extras.ubuntu.com/ubuntu/ xenial main

最后输入如下命令即可

   sudo apt-get update 更新源 
   sudo apt-get upgrade 更新软件
