大家好，我是Ubuntu新手，初来乍到，遇到一些问题，还请大家指点一下，谢谢！

最近在VMware上安装了Ubuntu 12.04.2 LTS,刚开始使用的时候一切都很正常，但是，最近，不知道怎么回事，一安装软件就会出错，我上google查了相关的出错信息，也按照上面的步骤去做了一遍，都无济于事，所以，在此向各位达人寻求帮助，请各位达人帮忙分析一下原因及如何解决？

问题描述如下：比如，我想安装dnsutils：

yaob@yaob-virtual-machine:~$ sudo apt-get install dnsutils
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
dnsutils : Depends: libbind9-80 (= 1:9.8.1.dfsg.P1-4ubuntu0.6) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is to be installed
Depends: libdns81 (= 1:9.8.1.dfsg.P1-4ubuntu0.6) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is to be installed
Depends: libisc83 (= 1:9.8.1.dfsg.P1-4ubuntu0.6) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is to be installed
Depends: libisccfg82 (= 1:9.8.1.dfsg.P1-4ubuntu0.6) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is to be installed
Depends: liblwres80 (= 1:9.8.1.dfsg.P1-4ubuntu0.6) but 1:9.8.1.dfsg.P1-4ubuntu0.5 is to be installed
libc6 : Recommends: libc6-i686
Breaks: locales (< 2.17) but 2.13+git20120306-3 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
yaob@yaob-virtual-machine:~$

此外，我试过google到的sudo apt-get clean; sudo apt-get update;方法
刚开始还很顺利，但到后面就出错了，这是出错信息。

有没有自己修改过源列表？

ubuntu怎么加了debian的源？真是乱来。
ubuntu确实是从debian构建的，但是不代表就能混在一起用啊

你好，现在我把源改为163的，但是，sudo apt-get update还是会出错，请问是怎么回事？

我尝试做了一个上午的操作，结果都不行，试了好多种方法：
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get update

结果出错：

前面那一个命令不是已经成功把40976EAF437D05B5给导入进去了吗？
请问我要怎么解决这个问题呢？我没有使用任何代理，深圳电信的网络。
非常感谢你前面的解答！

BADSIG 40976EAF437D05B5

可能这个是debian源里的public key，在ubuntu的源里没找到，所以报错了。只是猜测，现在已经不用ubuntu了
帮你顶一下，希望有人愿意测试一下吧

重装就好了，反正是虚拟机。

哦，好的。我再装一次。主要是之前都是因为同样的问题重装了3次，每次都不知道原因。现在知道原因了，那就再装一次吧，多谢！
