如何修复依赖/破坏包
当我尝试安装系统更新， skype或phpmyadmin出现此错误：
You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: libc6 : Depends: libgcc1 but it is not going to be installed Depends: tzdata but it is not going to be installed libc6-dev : Depends: libc-dev-bin (= 2.15-0ubuntu10.3) Depends: linux-libc-dev but it is not going to be installed Recommends: gcc but it is not going to be installed or c-compiler skype:i386 : Depends: libasound2:i386 (>= 1.0.16) but it is not going to be installed Depends: libc6:i386 (>= 2.3.6-6~) but it is not going to be installed Depends: libc6:i386 (>= 2.7) but it is not going to be installed Depends: libgcc1:i386 (>= 1:4.1.1) but it is not going to be installed Depends: libqt4-dbus:i386 (>= 4:4.5.3) but it is not going to be installed Depends: libqt4-network:i386 (>= 4:4.8.0) but it is not going to be installed Depends: libqt4-xml:i386 (>= 4:4.5.3) but it is not going to be installed Depends: libqtcore4:i386 (>= 4:4.7.0~beta1) but it is not going to be installed Depends: libqtgui4:i386 (>= 4:4.8.0) but it is not going to be installed Depends: libqtwebkit4:i386 (>= 2.1.0~2011week13) but it is not going to be installed Depends: libstdc++6:i386 (>= 4.6) but it is not going to be installed Depends: libx11-6:i386 but it is not going to be installed Depends: libxext6:i386 but it is not going to be installed Depends: libxss1:i386 but it is not going to be installed Depends: libxv1:i386 but it is not going to be installed Depends: libssl1.0.0:i386 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
怎么解决这个？
-f or --fix-broken
来自apt-get页面的解释
固定; 尝试纠正具有破坏的依赖关系的系统。 此选项与install / remove一起使用时，可以省略任何包以允许APT推断出可能的解决方案。 如果指定了包，则必须完全解决问题。 第一次运行APT时有时需要该选项; APT本身不允许在系统上存在破坏的包依赖性。 系统的依赖结构可能是如此腐败，以至于需要手动干预（这通常意味着使用dselect（1）或dpkg –remove来消除一些违规的包）。 在某些情况下，将此选项与-m一起使用可能会产生错误。 配置项：APT :: Get :: Fix-Broken。
我建议您尝试以下命令。
sudo dpkg --configure -a sudo apt-get install -f
对任何提示回答“是”，让apt-get尝试为您解决问题。
编辑：
根据评论尝试以下命令，它应该清理您的系统。
sudo sh -c "apt-get update;apt-get dist-upgrade;apt-get autoremove;apt-get autoclean"
