Ubuntu 12.04 LTS。如果需要更多信息，请告诉我，我会提供。
主要问题是：
tzach@tzach-pc:~$ sudo apt-get install docky
[sudo] password for tzach:
Reading package lists... Done
Building dependency tree
Reading state information... Done
docky is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
ca-certificates-java : Depends: openjdk-6-jre-headless (>= 6b16-1.6.1-2) but it is not going to be installed or
java6-runtime-headless
openjdk-7-jre-lib : Depends: openjdk-7-jre-headless (>= 7~b130~pre0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
tzach@tzach-pc:~$
并且：
tzach@tzach-pc:~$ sudo apt-get upgrade

**The following packages have unmet dependencies:
ca-certificates-java : Depends: openjdk-6-jre-headless (>= 6b16-1.6.1-2) but it is not installed or
java6-runtime-headless
openjdk-7-jre-lib : Depends: openjdk-7-jre-headless (>= 7~b130~pre0) but it is not installed
E: Unmet dependencies. Try using *******
因此我们尝试了消息#9中的指南：http://ubuntuforums.org/showthread.php?t=947124
我们运行所有前 4 个命令，最后一条命令“sudo apt-get autoremove”给了我们：
tzach@tzach-pc:~$ sudo apt-get autoremove

Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
**ca-certificates-java** : Depends: openjdk-6-jre-headless (>= 6b16-1.6.1-2) but it is not installed or
java6-runtime-headless
**openjdk-7-jre-lib** : Depends: openjdk-7-jre-headless (>= 7~b130~pre0) but it is not installed
E: Unmet dependencies. Try using -f.
因此我们运行最后一个命令两次：sudo dpkg --remove -force --force-remove-reinstreqca-证书-java 和 sudo dpkg --remove -force --force-remove-reinstreqopenjdk-7-jre-lib
但两者都给出了：
tzach@tzach-pc:~$ sudo dpkg --remove -force --force-remove-reinstreq ca-certificates-java
[sudo] password for tzach:
dpkg: error: conflicting actions -f (--field) and -r (--remove)
Type dpkg --help for help about installing and deinstalling packages [*];
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Options marked [*] produce a lot of output - pipe it through `less' or `more' !
编辑 green7-“sudo apt-get -f install”的输出：

尝试这个
sudo mv /var/lib/dpkg/info/tzdata.prerm ~/tzdata.prerm
sudo dpkg-reconfigure tzdata --force
sudo dpkg --purge --force-all tzdata
答案2
tzdata尝试删除可能导致问题的包：
sudo apt-get remove --purge tzdata
答案3
尝试
rm /var/lib/apt/lists/* -vf
apt-get update
答案4
我在软件包方面遇到了一些不同的问题，但通过以下方法解决了：
sudo dpkg --remove <conflicted-package-name>
sudo apt-get install -f
并且已经修复。
