处理时遇到错误：man-db

apt-get upgrade & apt-get autoremove在每次使用以及apt-get [Something]..尝试安装应用程序时，也会出现此错误：

Errors were encountered while processing:
man-db
E: Sub-process /usr/bin/dpkg returned an error code (1)

请阅读下面的评论。在系统上运行并创建不可恢复的状态，这可能是危险的命令。（这些行已被注释掉，以防止复制和粘贴sysadmin'ing）。

简单和工作，我尝试了！

sudo -s
# cd /var/cache/debconf
# rm *.dat
apt-get update && apt-get upgrade

请享用 ;）

答案中没有提到的解决方案对我有用，我在Ubuntu论坛上尝试了此处提到的解决方案，执行命令

sudo dpkg -i --force-all [deb file path]

并且有效。

社区Wiki答案-由OP解决

通过运行以下终端命令解决了此问题：

sudo dpkg-reconfigure -phigh -a

您可能还想知道可以dpkg --audit用来查看实际问题是什么。

如果输出是这样的：

The following packages are in a mess due to serious problems during installation. 
They must be reinstalled for them (and any packages that depend on them) 
to function properly:
  gcdemu A GNOME panel applet to control CDEmu daemon

The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
 cdemu-daemon CDEmu daemon
 cdemu-client A simple command-line client to control CDEmu daemon

The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
 transmission-daemon lightweight BitTorrent client (daemon)
 vhba-dkms VHBA virtual host bus adapter module

您可以运行以下命令： dpkg --configure <packagename>

 dpkg --configure cdemu-daemon

为了

Reconfigure an unpacked package. 
If -a  or  --pending  is  given instead of package, all unpacked but unconfigured
packages are configured.

此外，您可以使用：

sudo apt-get -f install
sudo apt-get --reinstall install gcdemu

修复混乱的软件包。

此处的示例：http : //ubuntuforums.org/archive/index.php/t-1502826.html

您必须在命令前加上sudo来运行这些命令，以便可以使用超级用户凭据执行这些命令。示例：

sudo apt-get autoremove "NAME OF PACKAGE HERE"

如果您删除/var/cache了误导性的清理尝试（如我所做的那样），则可能会解决问题（对我而言确实如此）：

sudo mkdir /var/cache/debconf
