Above is actually a regression, which causes sbuild to fail when using
AptResolver when cross-compiling. I don't know if "-f" actually does
anything when above command is invoked.

As per manpage all options apply to all sub-commands, and there are no
per sub-command options/restrictions. ( [-asqdyfmubV] )

specifically, why is "-f" rejected yet at the same time:
    apt-get -oAPT::Get::Fix-Broken=true --purge -y build-dep hello
is accepted?

Similarly "--purge" had to be unbroken, see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720597

Removing options, breaks compatibility, thus shouldn't be done in a
point release of such a core utility which is used in scripts.

Dmitrijs.

Title:
  apt-get --purge -yf build-dep hello, fails with E: Command line option
  ‘f’ [from -yf] is not known.

Status in “apt” package in Ubuntu:
  Confirmed

Bug description:
  apt-get --purge -yf build-dep hello, fails with E: Command line option
  ‘f’ [from -yf] is not known.

  this thus breaks sbuild cross-builds. another regression ?
