dpkg-divert - override a package's version of a file
is the utility used to set up and update the list of diversions.
File diversions are a way of forcing
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.
- [--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.
- --admindir directory
Set the dpkg data directory to directory (default:
- --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
- --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
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 demonstrate.
- -?, --help
Show the usage message and exit.
Show the version and exit.
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 name.
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.
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(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.
To divert all copies of a /usr/bin/example
i.e. directs all packages providing /usr/bin/example
to install it as
, 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
