Comment 6 for bug 1341611

From man:

apt-get [-sqdyfmubV] [-o= config_string ] [-c= config_file ]
               [-t= target_release] [-a= default_architecture] {update |
               upgrade | dselect-upgrade | dist-upgrade |
               install pkg [ { =pkg_version_number | /target_release } ] ...
               | remove pkg... | purge pkg... |
               source pkg [ { =pkg_version_number | /target_release } ] ... |
               build-dep pkg... | check | clean | autoclean | autoremove |
               {-v | --version} | {-h | --help}}

The opcon "f" is a general purpose follows the comand like all of these [ -sqdyfmubV] and therefore can be used with all commands such as "update, upgrade, autoclean, etc".

The specific section for the orders "install/remove" does not specify "any particular option" for these orders. You can use the symbols +, - , = , /,etc and package name, version, etc but, I repeat, "no option specifies". Check out the man:

               install pkg [ { =pkg_version_number | /target_release } ] ...
               | remove pkg... | purge pkg... |

 install
           install is followed by one or more packages desired for
           installation or upgrading. Each package is a package name, not a
           fully qualified filename (for instance, in a Debian GNU/Linux
           system, libc6 would be the argument provided, not
           libc6_1.9.6-2.deb). All packages required by the package(s)
           specified for installation will also be retrieved and installed.
           The /etc/apt/sources.list file is used to locate the desired
           packages. If a hyphen is appended to the package name (with no
           intervening space), the identified package will be removed if it is
           installed. Similarly a plus sign can be used to designate a package
           to install. These latter features may be used to override decisions
           made by apt-get's conflict resolution system.

           A specific version of a package can be selected for installation by
           following the package name with an equals and the version of the
           package to select. This will cause that version to be located and
           selected for install. Alternatively a specific distribution can be
           selected by following the package name with a slash and the version
           of the distribution or the Archive name (stable, testing,
           unstable).

           Both of the version selection mechanisms can downgrade packages and
           must be used with care.

           This is also the target to use if you want to upgrade one or more
           already-installed packages without upgrading every package you have
           on your system. Unlike the "upgrade" target, which installs the
           newest version of all currently installed packages, "install" will
           install the newest version of only the package(s) specified. Simply
           provide the name of the package(s) you wish to upgrade, and if a
           newer version is available, it (and its dependencies, as described
           above) will be downloaded and installed.

           Finally, the apt_preferences(5) mechanism allows you to create an
           alternative installation policy for individual packages.

           If no package matches the given expression and the expression
           contains one of '.', '?' or '*' then it is assumed to be a POSIX
           regular expression, and it is applied to all package names in the
           database. Any matches are then installed (or removed). Note that
           matching is done by substring so 'lo.*' matches 'how-lo' and
           'lowest'. If this is undesired, anchor the regular expression with
           a '^' or '$' character, or create a more specific regular
           expression.

       remove
           remove is identical to install except that packages are removed
           instead of installed. Note the removing a package leaves its
           configuration files in system. If a plus sign is appended to the
           package name (with no intervening space), the identified package
           will be installed instead of removed.

There is a bug
