安装GPG密钥：
wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
确保apt被设置为与https源一起工作：
sudo apt-get install apt-transport-https
选择要使用的频道：
稳定版本(常用)
echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
开发版本(和稳定版二者选一)
echo "deb https://download.sublimetext.com/ apt/dev/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
更新apt源并安装Sublime Text
sudo apt-get update
sudo apt-get install sublime-text
