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.

或者
Errors were encountered while processing: cups-browsed 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 install Reading 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。
