sudo apt-get -f install究竟做了什么？
我以前见过它。 我只是想知道它到底是做什么的？
来自man apt-get ：
-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.
这是我发现它非常有用的地方。 我运行了一个dpkg命令来安装几个.deb软件包，但安装失败，因为缺少一些依赖项。
然后我跑了
apt-get -f install
它安装了所需的依赖项。 然后我能够重新运行我的dpkg命令，一切正常。
