shiftSource.sh

#!/usr/bin/env bash
## 制定脚本执行的是bash shell，强烈建议明确shell，否则脚本执行可能出现意外

## 处理命令之后回显，以便调试脚本
#set -o xtrace

## 强制切换到root权限执行脚本
if [ `whoami` != "root" ]; then
    sudo passwd root
    exec su -c 'sh ./shiftSource.sh'
fi

## 如果最近一次的apt-get install强制中断，修复apt-get install锁定导致不能进行新的安装
if [ -e /var/cache/apt/archives/lock ]; then
rm -rf /var/cache/apt/archives/lock
fi
if [ -e /var/lib/dpkg/lock ]; then
rm -rf /var/lib/dpkg/lock
fi
if [ -e /var/lib/apt/lists/lock ]; then
rm -rf /var/lib/apt/lists/lock

## 切换软件包源，并更新本地的软件包列表
