由于多次安装Ubuntu16.04用于学习，其中出了多次问题。每次找参考文件太麻烦，于是写了这篇总结，方便之后备用。
一、精简系统，删除不常用软件

1、删除libreoffice
sudo apt remove libreoffice-common
2、删除Amazon的链接
sudo apt-get remove unity-webapps-common
3、卸载火狐
首先，查看火狐有哪些安装包：
dpkg --get-selections |grep firefox
然后，依次卸载：
sudo apt-get purge firefox firefox-locale-en firefox-locale-zh-hans
4、删掉基本不用的自带软件
sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install sudo apt-get remove onboard deja-dup
二、做一些配置工作
1、安装Vim
sudo apt-get install vim
2、更换国内源
1.备份系统自带源
mv /etc/apt/sources.list /etc/apt/sources.list.bak
2.修改/etc/apt/sources.list文件
vim /etc/apt/sources.list
3.加入国内源
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties deb http://mirrors.aliyun.com/ubuntu/ xenial universe deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties deb http://archive.canonical.com/ubuntu xenial partner deb-src http://archive.canonical.com/ubuntu xenial partner deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse
4.更新生效
apt-get update
3、安装Sublime Text 3
1、通过apt安装：
2、安装GPG key:
wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
3、确保apt能够使用https源
sudo apt-get install apt-transport-https
4、使用稳定版源
echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
5、更新apt源并安装sublime-text，并打开
sudo apt-get update sudo apt-get install sublime-text
subl

7、安装Packeage Contro
sublime Text 3 打开按shift+`按键打开控制台将下边代码贴进去：
import urllib.request,os,hashlib; h = '7183a2d3e96f11eeadd761d777e62404' + 'e330c659d4bb41d3bdf022e94cab3cd0'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://sublime.wbond.net/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)
