折腾了一下午装了一个Ubuntu系统，感觉界面干净，系统流畅 电脑是双系统，用easyBCD做引导时手贱～把win10引导给删了，win10现在进不了 网上还没有找到解决方法，现在不管了，先熟练这linux操作几天再处理下，要不删了win10～～～ CTRL+ALT+T ------> 调出终端快捷键 sudo i / sudo root -------> 进入管理 sudo apt-get install xxx --------> 安装源包 修改源地址： 图形界面修改->Ubuntu软件中心->编辑->软件源->下载地->其他 终端，输入命令： sudo gedit /etc/apt/sources.list 然后更新： sudo get-apt update cp /etc/apt/sources.list /etc/apt/sources.list.bak vim /etc/apt/sources.list 加入如下内容（中科大的）： deb http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted deb http://mirrors.ustc

打开Terminal终端：Ctrl + Alt + T 按顺序执行以下三条命令： sudo add-apt-repository ppa:nilarrimogard/webupd8 sudo apt-get update sudo apt-get install android-tools-adb android-tools-fastboot 安装过程如果出现需要安装其他的组件，就按照提示安装即可。 安装后，将手机设置成USB调试模式，通过数据线接至pc机。 执行如下命令测试adb的安装是否成功： adb devices 如下是我安装的过程： wangjie@wangjie-A8Se:~$ sudo add-apt-repository ppa:nilarimogard/webupd8 [sudo] password for wangjie: //输入密码获取root权限 You are about to add the following PPA to your system: The main Web Upd8 PPA maintained by: http://www.webupd8.org/ To add this PPA, simply paste this in a terminal: sudo add-apt-repository ppa:nilarimogard
