dpkg-divert - override a package's version of a file
is the utility used to set up and update the list of
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
installing a newer version of a package which contains those files.
- [--add] file
- Add a diversion for file.
- --remove file
- Remove a diversion for file.
- --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.
- --admindir directory
- Set the dpkg data directory to directory
- --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.
- Test mode, i.e. don't actually perform any changes, just
- -?, --help
- Show the usage message and exit.
- Show the version and exit.
- The requested action was successfully performed.
- Fatal or unrecoverable error due to invalid command-line
usage, or interactions with the system, such as accesses to the database,
memory allocations, etc.
- If set and the --admindir option has 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
- 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.
When adding, default is --local
. When removing, --package
must match if specified.
Directories can't be diverted with dpkg-divert
Care should be taken when diverting shared libraries, ldconfig
a symbolic link based on the DT_SONAME field embedded in the library. Because
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.
To divert all copies of a /usr/bin/example
, i.e. directs all packages providing
to install it as /usr/bin/example.foo
performing the rename if required:
--divert /usr/bin/example.foo --rename /usr/bin/example
To remove that diversion:
--rename --remove /usr/bin/example
To divert any package trying to install /usr/bin/example
, except your own wibble
--package wibble --divert /usr/bin/example.foo --rename /usr/bin/example
To remove that diversion:
--package wibble --rename --remove /usr/bin/example
