什么是sudo apt-get -f install？
apt-get -f install的用法是什么？ 当我运行sudo apt-get update我在最后遇到了一些错误它说试试apt-get -f install 。 这个命令是什么？ 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).
请参阅联机帮助页 ：
-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.
