dpkg-divert(1)                              dpkg suite                             dpkg-divert(1)

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

SYNOPSIS
       dpkg-divert [option...]  command

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

       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
       [--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 diversions 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
       --admindir directory
              Set the administrative directory to directory.  Defaults to «/var/lib/dpkg».

       --instdir directory
              Set  the  installation  directory, which refers to the directory where packages get
              installed (since dpkg 1.19.2). Defaults to «/».

       --root directory
              Set the root directory to directory,  which  sets  the  installation  directory  to
              «directory»  and  the  administrative  directory to «directory/var/lib/dpkg» (since
              dpkg 1.19.2).

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

       --local
              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
              Quiet mode, i.e. no verbose output.

       --rename
              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
              details).

       --no-rename
              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 Test mode, i.e. don't actually perform any changes, just demonstrate.

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

       --version
              Show the version and exit.

EXIT STATUS
       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
       DPKG_ROOT
              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).

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

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

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

FILES
       /var/lib/dpkg/diversions
              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 available.
              Note: dpkg-divert preserves the old copy of this file, with extension -old,  before
              replacing it with the new one.

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

       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 doesn't honour
       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
       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
