在 Ubuntu 执行 sudo apt-get upgrade 时，出现了如下的报错：
Setting up bluez (4.101-0ubuntu13.1) ...reload: Job is not running: dbus invoke-rc.d: initscript dbus, action "force-reload" failed. start: Job failed to start invoke-rc.d: initscript bluetooth, action "start" failed. dpkg: error processing package bluez (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of bluez-alsa:i386: bluez-alsa:i386 depends on bluez; however: Package bluez is not configured yet. dpkg: error processing package bluez-alsa:i386 (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure. Errors were encountered while processing: bluez bluez-alsa:i386 E: Sub-process /usr/bin/dpkg returned an error code (1)
通过执行下面的命令可以解决该问题：
$ sudo mv /var/lib/dpkg/info/ /var/lib/dpkg/info_old/$ sudo mkdir /var/lib/dpkg/info/$ sudo apt-get update...$ sudo apt-get -f installReading package lists...

输入上述命令之后，在执行 sudo apt-get update 和 sudo apt-get upgrade 就不会有问题了。
现在终于把系统从Window换到Ubuntu，还是蛮高兴的，结果还没有高兴一上午就出问题了。
原因是出再Flash插件上，我打开Firefox时候，它一直推荐我装，我就默认安装了。结果坏了大事情，可能是因为公司网速，下带一半就卡住，我就取消了，结果这个时候，我的dpkg就锁住了。后来，征求我们这边一位仁兄的意见，采用dpkg重置命令。
（注意：系统推荐是 sudo dpkg configure -a）
我就输入 sudo dpkg-reconfigure -phigh -a
静静等待一段时间，系统包依赖关系都整理，一切恢复到之前的状态，包管理器有可以用了。
另外我说一下 FLASH插件安装
1，去ADOBE官网去下包，这里推荐下Linux tar.gz的包。
2，解压，会出现一个文件夹和一个so文件，这个so文件才是我们要的。
3，将so文件移动到 /usr/lib/mozilla/plugins/ 下面就可以了，现在你的Flash就装好了。
