Synopsis
dpkg-divert
[option...] command
add an example, a script, a trick and tips
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

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.
options
--admindir
directory
Set the dpkg data directory to
directory (default: /var/lib/dpkg).
--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.
--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.
commands
[--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. Prints
LOCAL if file is locally diverted and nothing if
file is not diverted.
--truename file
Print the real name for a diverted file.
environment
DPKG_ADMINDIR
If set and the --admindir option has 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.
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.
