在 Ubuntu 執行 sudo apt-get upgrade 時，出現了如下的報錯：
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)
或者
Errors were encountered while processing: cups-browsed E: Sub-process /usr/bin/dpkg returned an error code (1)
通過執行下面的命令可以解決該問題：
$ 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... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 7 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Setting up bluez (4.101-0ubuntu13.1) ... Setting up blueman (1.23-git201403102151-1ubuntu1) ...

輸入上述命令之后，在執行 sudo apt-get update 和 sudo apt-get upgrade 就不會有問題了。
