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
