به نقل از 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 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.
