什么是 sudo apt-get -f install？

有什么用apt-get -f install。运行时，sudo apt-get update最后出现一些错误，它说尝试apt-get -f install。这是个什么命令？我的错误的最后一部分是：

. . .  
going to be installed  
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

查看手册页：

-f, --fix-broken
   Fix; attempt to correct a system with broken dependencies in place.
   This option, when used with install/remove, can omit any packages
   to permit APT to deduce a likely solution. If packages are
   specified, these have to completely correct the problem. The option
   is sometimes necessary when running APT for the first time; APT
   itself does not allow broken package dependencies to exist on a
   system. It is possible that a system's dependency structure can be
   so corrupt as to require manual intervention (which usually means
   using dselect(1) or dpkg --remove to eliminate some of the
   offending packages). Use of this option together with -m may
   produce an error in some situations. Configuration Item:
   APT::Get::Fix-Broken.

这是尝试解决 umet 依赖关系时的首批解决方案之一。（请参阅此问题：添加 PPA 后如何解决未满足的依赖关系？）
