NAME         top

       dpkg-divert - override a package's version of a file

SYNOPSIS         top

       dpkg-divert [option...]  command

DESCRIPTION         top

       dpkg-divert is the utility used to set up and update the list of

       File diversions are a way of forcing dpkg(1) not to install a
       file into its location, but to a diverted location. Diversions
       can be used through the Debian package scripts to move a file
       away when it causes a conflict. System administrators can also
       use it to override some package's configuration file, or whenever
       some files (which aren't marked as “conffiles”) need to be
       preserved by dpkg, when installing a newer version of a package
       which contains those files.

COMMANDS         top

       [--add] file
           Add a diversion for file.  The file is currently not renamed,
           see --rename.

       --remove file
           Remove a diversion for file.  The file is currently not
           renamed, see --rename.

       --list [glob-pattern]
           List all diversions, or ones matching glob-pattern.

       --listpackage file
           Print the name of the package that diverts file (since dpkg
           1.15.0).  Prints LOCAL if file is locally diverted and
           nothing if file is not diverted.

       --truename file
           Print the real name for a diverted file.

OPTIONS         top

       --admindir directory
           Set the administrative directory to directory.  Defaults to
           «/usr/local/var/lib/dpkg» if DPKG_ADMINDIR has not been set.

       --instdir directory
           Set the installation directory, which refers to the directory
           where packages get installed (since dpkg 1.19.2).  Defaults
           to «/» if DPKG_ROOT has not been set.

       --root directory
           Set the root directory to directory, which sets the
           installation directory to «directory» and the administrative
           directory to «directory/usr/local/var/lib/dpkg» (since dpkg
           1.19.2) if DPKG_ROOT has not been set.

       --divert divert-to
           divert-to is the location where the versions of file, as
           provided by other packages, will be diverted.

           Specifies that all packages' versions of this file are
           diverted.  This means, that there are no exceptions, and
           whatever package is installed, the file is diverted. This can
           be used by an admin to install a locally modified version.

       --package package
           package is the name of a package whose copy of file will not
           be diverted. i.e. file will be diverted for all packages
           except package.

           Quiet mode, i.e. no verbose output.

           Actually move the file aside (or back). dpkg-divert will
           abort operation in case the destination file already exists.
           This is the common behavior used for diversions of files from
           the non-Essential package set (see --no-rename for more

           Specifies that the file should not be renamed while adding or
           removing the diversion into the database (since dpkg 1.19.1).
           This is intended for diversions of files from the Essential
           package set, where the temporary disappearance of the
           original file is not acceptable, as it can render the system
           non-functional.  This is the default behavior, but that will
           change in the dpkg 1.20.x cycle.

           Test mode, i.e. don't actually perform any changes, just

       -?, --help
           Show the usage message and exit.

           Show the version and exit.

EXIT STATUS         top

       0   The requested action was successfully performed.

       2   Fatal or unrecoverable error due to invalid command-line
           usage, or interactions with the system, such as accesses to
           the database, memory allocations, etc.

ENVIRONMENT         top

           If set and the --instdir or --root options have not been
           specified, it will be used as the filesystem root directory
           (since dpkg 1.19.2).

           If set and the --admindir or --root options have not been
           specified, it will be used as the dpkg data directory.

           If set and the --local and --package options have not been
           specified, dpkg-divert will use it as the package name.

           Sets the debug mask (since dpkg 1.21.10) from an octal value.
           The currently accepted flags are described in the dpkg
           --debug option, but not all these flags might have an effect
           on this program.

           Sets the color mode (since dpkg 1.18.5).  The currently
           accepted values are: auto (default), always and never.

FILES         top

           File which contains the current list of diversions of the
           system. It is located in the dpkg administration directory,
           along with other files important to dpkg, such as status or

           Note: dpkg-divert preserves the old copy of this file, with
           extension -old, before replacing it with the new one.

NOTES         top

       When adding, default is --local and --divert original.distrib.
       When removing, --package or --local and --divert must match if

       Directories can't be diverted with dpkg-divert.

       Care should be taken when diverting shared libraries, ldconfig(8)
       creates a symbolic link based on the DT_SONAME field embedded in
       the library.  Because ldconfig does not honor diverts (only dpkg
       does), the symlink may end up pointing at the diverted library,
       if a diverted library has the same SONAME as the undiverted one.

EXAMPLES         top

       To divert all copies of a /usr/bin/example to
       /usr/bin/example.foo, i.e. directs all packages providing
       /usr/bin/example to install it as /usr/bin/example.foo,
       performing the rename if required:

        dpkg-divert --divert /usr/bin/example.foo --rename /usr/bin/example

       To remove that diversion:

        dpkg-divert --rename --remove /usr/bin/example

       To divert any package trying to install /usr/bin/example to
       /usr/bin/example.foo, except your own wibble package:

        dpkg-divert --package wibble --divert /usr/bin/example.foo \
           --rename /usr/bin/example

       To remove that diversion:

        dpkg-divert --package wibble --rename --remove /usr/bin/example
